interesting experiment!! maybe you could use oobleck as a delay. could you use it for booster rockets and main stage? if you find out when the main stage disonnects from the launcher rockets and launches further in min air, then once you know you could accordingly put enough oobleck in the rocket for specific amount of time before the main stage launches away from the booster rocket.
the oobleck is under so much pressure that it is causing it to become a solid plug rather than a liquid; only when the pressure decreases enough does it allow the solid to loosen enough for air to escape.
Hello, my name is David I am 38 years old and I'm from Mallorca (Spain), I love your channel and I learning a lot. I make a few differents Water Rockets with success, but I need your help to my new project. I only have 3 weeks to make a new Super Water Rocket to my son birthday,(4 years) and I only have time to make one prototype. My idea is make a big nose capsule (like falcon 9 more or less) with 2 escape doors, one with a big parachute and second one to color tapes or confetti). I think I will put 3 bottle's 2.2l or 4 bottle's 2l and then the capsule, but I can put in only 6'5 bars pressure, and the deflecting nozzle is 8mm. My question is, How much weight can I put in the noise capsule and how many water can I put with 6'5 pressure? Of course I can change the design or the bottle depending of your opinion. Thanks.
What size nozzle will you use? What is the total capacity (pressurised volume) of the rocket if you are putting those bottles together? 6L. 8L? For a 6L rocket at 6.5 bar and a 22mm nozzle, 2 liters of water and a total weight of the empty rocket and payload 1000g will give you roughly an altitude of: 60m, Your rocket will weigh say 350 grams, and a payload of 650 grams. With a payload of 1Kg (1350g total weight) will give you an altitude of ~40m
@@AirCommandRockets The nozzle is 8mm, I using a standard pipe garden connector. My idea is put 3 bottles 2'2l, total pressure volume 6'6l, but I can change depending your opinion. Thanks
Its only when you do things outside the envelope that you may find an exciting discovery or effect because no one else will bother. Good on you mate thats the way to do it.
Any chance that the reason for the solid left behind was that the pressure release of launch drove a lot of the water out, leaving more dry cornstarch in the rocket?
+Samuel Dale Quite possibly. I noticed that the Oobleck dries very rapidly when it is thinned out on things, but these were decent sized chunks. I also wondered whether the rapid depressurisation and/or the associated drop in temperature also maybe had something to do with it, but I think you are closer to mark.
Hi Ed, Do you mean add salt to increase the liquid density? Higher density will not necessarily lead to higher altitude. See here for an earlier experiment where we looked at different density liquids: ruclips.net/video/Fu3rIiPy_18/видео.html
Thanks +biggles1024 We really didn't know what would happen before we tried it. I was just glad it didn't pop off the launch rail, otherwise it may have made a nice "land shark". :)
This isn't that surprising if you knew how Oobleck acted. When you apply sudden, hard pressure to Oobleck, it acts as a solid. With it being pressurized in a tank and forced through a small nozzle, it became a solid and would not pass quickly. Try looking up liquids with less viscosity and see how those perform. I did a little looking up and water is the most common, least viscos liquid but Im sure with enough looking you can find another.
if you mix olive oil with corn flower it is like oobleck when you pass a voltage thru it, it goes hard until you power down, then it returns to a normal liquid state again, mmm I wonder how you could use that, an electrically excited stir thickening semi solid liquid organic compostable product that when discarded rots and feeds bugs
Good videos:) Try to boil a few spoons of corn or potato starch in water to make a "water custard". When launching, you want to throw as much mass as you can, and as fast as you can out the nossle. Starch might not help very much with that, but maybe a water custard can hold sand, or even iron powder in suspension, to make the liquid heavier than water alone per volume. Another suggestion to make a heavier liquid is to dissolve salt in the water. In the same volume you could have a liquid that is maybe 20+ % heavier, and still very viscous.
p Interesting test I watched this after doing this experiment and I achieved a higher altitude then my usual water rocket after some experimenting. I would recommend using a larger nozzle or no nozzle at all and using much less ubleck
The non-Newtonian property of oobleck is shear thickening, which makes it harder for it to shear the more force you apply. It might also be interesting to experiment with the opposite, namely shear thinning. One example would be ketchup. A quick search shows that it is caused by xanthan gum.
You are right.. it was cool... it looks like they should have used less of the 'oobleck'... though I know little about the process! lol... kind of like the new detergent that you only have to use a little to do a lot... I say this based on the fact in both tests the rocket didn't actually launch until the substance had almost leaked out... very cool though.
A heavy [non-toxic] salt our sugar type material would make a good way to increase propellant mass without adversely affecting density or air-to-propellant volumetric ratios. Picking something with a high solubility rate [like calcium chloride or magnesium chloride] would allow you to add even more water than with just water alone because of the way hydrates www.sciencemadness.org/smwiki/index.php/Density [this list shows more than what one would be looking for, but still it would show you various safe options between the not-so-safe options, so its just a case of finding safe ones and trying them out on a small scale.
A heavier propellant mass doesn't necessarily increase performance. Although you generate higher thrust, you also have a heavier rocket to lift with the heavier liquid still in the rocket. Lower density liquids like alcohol can improve performance. ruclips.net/video/Fu3rIiPy_18/видео.html
Alcohol is indeed lower in density, but its poisonous and highly flammable, so that would seem to be a consideration based on how it is being launched. Okay, so I watched the video, and while it would seem that the results would have proven me wrong, it is of course based on some unknowns which I would have to play around with to see if 'all things being equal' were truly equal. I have only really and seriously worked with solid fuel rockets, so this is all pretty new to me despite knowing how water rockets work [my childhood playing with water rockets was not remotely scientific so I do not count those] in principle, so it looks like starting from somewhere near where your work has begun, I should become familiar with the process and develop some good baselines before attempting to experiment. If I ever get time to do any of this, since what I have are American sized 2 liter bottles and 3 liter bottles [and I literally have hundreds of them!] my initial results will likely be significantly different and as such I will have to begin by establishing my baseline from scratch. At least I have a machine shop to make nozzles, launchers and valves. One big drawback to larger bottles, of course, is that they tend to not handle pressure as well due to the fundamental laws of pressure and material fatigue. I may end up making a fiberglass body, hard to say.
hey this is a cool vid keep up the good work i just made my luncher for my water rocket me and my dad flow it and it put a hole throw are tin roof on are deck and that was with out water or foam
2:13 that rocket launching brought back some bad memories of the time i got hashbrowns from sheets. that shit had me constipated on the toilet and all at once it shot out with great force about sent me taking off into the bath tub.
..don´t really see your point to use this mix as propellant. It seems quiet logic that it will behave with strong motion resistance - like you demonstrated at first. Anyway - seems like a really nice waste of time...
Try filling the water rocket with Isopropyl rubbing alcohol, I hear there is a 99% one available. Place at least 4 alcohol lamps around the base of the rocket and light them just before launch.

I've tried a thinner solution once (probably 8 parts water, 2 parts starch). It flew, and it looked more like the 100s and 1000s launch. Kudos!
+Maru Ivan Rico Cool. Did it exhibit the same properties when you hit the solution, or was it quite runny?
How about salt? Salt should increase the mass of the propelled liquid while keeping the fluid properties of water. Or has this been done before?
Hi Ed, Do you mean add salt to increase the liquid density? Higher density will not necessarily lead to higher altitude. See here for an earlier experiment where we looked at different density liquids: ruclips.net/video/Fu3rIiPy_18/видео.html

Thanks +biggles1024 We really didn't know what would happen before we tried it. I was just glad it didn't pop off the launch rail, otherwise it may have made a nice "land shark". :)
Have you tried a denser fluid but less viscous propellant, such as strong brine, to get more reaction per unit volume?
Mercury!
How did you make the rocket and parachute
Soo cool never new oobleck could do such a thing.
How about using liquid nitrogen or a gas that is liquid under pressure?
This isn't that surprising if you knew how Oobleck acted. When you apply sudden, hard pressure to Oobleck, it acts as a solid. With it being pressurized in a tank and forced through a small nozzle, it became a solid and would not pass quickly. Try looking up liquids with less viscosity and see how those perform.

Methanol has a lower viscosity than water.
the corn starch turned solid as the internet pressure was released vaporising the remaining water
internet pressure, heh :)

can you please try it with gas aka butane , or petrol with a candle underneath
+ninejets Unfortunately No. That is way too dangerous.
AirCommandRockets Would be cool tho ! id do it and stand faar back if i knew how to make those rockets
+ninejets I would still discourage you from trying. Lots of fun to be had with regular water rockets. :)
AirCommandRockets ah fine , is there a guide on how to build one anywhere?
+ninejets www.aircommandrockets.com/construction_index.htm
I think if you add more pressure it would have worked better maybe
what if you use a medium with a lower specific gravity than water, say rubbing alcohol at 90%.
Here is an experiment where we do exactly that. The difference is measurable. :) ruclips.net/video/Fu3rIiPy_18/видео.html
Bears some resemblance to launches during development days of Atlas rockets back in the 1950s I think it was.
You mean the short take-off quickly followed by falling back onto the launch pad? :)
Yes exactly!

Actually if it is kept dry, then it should make a reasonable fuel. See here: ruclips.net/video/YUeDsy64H6U/видео.html
