Had the same experience when we tried to dye the red vex gears. Compared with the green gears the red ones looked slightly purple. The 84s were especially tough to dye
OK VEX teams, please please please do not do this in your parent's kitchen! If you want to risk an acetone explosion and dying a kitchen with permanent black dots, wait until you buy your own house to ruin and you have your own health insurance to pay for your emergency room visit. Do this outside in the grass on an old chair with an electric hotplate (old coffeemaker or the like) and NOT on an open flame gas burner. Acetone is highly flammable. It evaporates at room temp but the heating source makes it rapidly boil off. This is why you have to add more after you do another batch of parts - it all boils off. There will be a lot of flammable vapor - another reason you need to do this outside. Please wear safety goggles or a full shield facemask so at least your eyes don't get burned out if something does go wrong. You need to control the temp so the mixture (mainly the water) doesn't boil over out of control. You can easily do this with a double boiler setup - put water in a pot and heat that directly, then put another pot in the boiling water with the dye. Doing this, your dye mix won't get over 200 degrees and the water in the mix itself will never boil (the acetone will boil but not the water). Make sure your pots are twice as deep as your solution so there is no chance of boilover. Boilovers can cause ignition of the acetone. When you add more acetone/water mix, it will rapidly boil/foam up multiple inches above the existing solution. You should be very afraid if a boilover happens - run away and disconnect the power to the hotplate. You can use stainless steel pots and tongs, the dye will not stain them. Although your mom will probably get upset if you try to use her expensive Caphalon pots. Look at the Rit Dye bottle in the video and buy the Dye More version. This is a synthetic dye. Regular Rit dye will not work. We mixed about 4 oz of dye and 4 of acetone in 8oz of water to start out, then added more acetone/water (50:50 mix) with the 2nd and 3rd batch of gears. Green gears dye within minutes, but red gears take 10 to 15 mins. We left the red gears in the bottom and just cycled the green gears in/out and pulled the red gears out last. Lay the dyed gears out on an old towel and let them dry overnight. Then the next day wash the gears with soap, water, and a toothbrush to clean off any non-absorbed latent dye so you won't dye your hands handing them. Good luck!
How did you get the light blue color on those gears at the start of the video? The teeth still look green so I'm wondering if you just put masking tape around the teeth and spraypainted the center or if there is a reliable way to get that color with dye. Thanks!
if we were to dye omnis, would you suggest to just dye the whole wheel and have the color run out of the rollers. or remove the rollers and just dye the hub
So very cool! I definitely don’t want to miss another video from 60470S Semicolon!
That’s what I’m sayin
glad to see other teams doing this. first saw it on 62A a while ago. great bot, great video.

or just use spray paint instead of allat
@@redfire7820 spray painting your gears is terrible cause it will never mesh together properly, it causes a ton of friction and it chips off
Can you do a video on how to paint vex metal. Or the best way to do so
Sure :)
How to metal spray dye for color full metal with powder rit tutorial please

How good will dyeing the parts white turn out
if we were to dye omnis, would you suggest to just dye the whole wheel and have the color run out of the rollers. or remove the rollers and just dye the hub
We have dyed the whole wheel many times and it works just fine.
@@6047OSSemicolon splendid, thank you
Do you think i could dye the green gears a light blue
imagine dying the nameplates black though
Would there be someway to bleach the gears or other plastic parts to a white ish base so it'll dye better?
We tried bleaching the gears and it did not work maybe another chemical would though.
@@6047OSSemicolon
Can I cook the metal too
sure :)
It won't actually dye though. To color metal either use paint or get a company to anodize it for you.
How long does it usually take
whoa very cool
The org I’m in (295) does this and one time we forgot about the gears on the stove and all that was left was the metal cores 😭
Why the acetone?
It helps dye the plastic better by essentially making extremely small imperfections on the surface which the dye can bond with.
tasty chemicals
yall are ventilating that space right?
Acetone fume smell nice :)
