Witchcraft - Appalachian folk song
If there were witchcraft
I'd make two wishes
A winding road that beckons me to roam
And then I'd wish for
A blazing campfire
To welcome me
When I'm returning home
But in this real world
There is no witchcraft
And golden wishes do not grow on trees
Our fondest daydreams
Must be the magic
To bring us back
Our happy memories
I'd make two wishes
A winding road that beckons me to roam
And then I'd wish for
A blazing campfire
To welcome me
When I'm returning home
But in this real world
There is no witchcraft
And golden wishes do not grow on trees
Our fondest daydreams
Must be the magic
To bring us back
Our happy memories

How to color this ball you made? Please do a video. Thank you
Kid, you're so smart, you scare me! LOL
Bonjours Ou acheter les billes expancer.merci ?
How would you call these beads as poly styrene beads it seems are nowhere available
Why do some people enlarge it to half its original size, then put it in a mold, then enlarge the foam to the largest size?
To reduce cost. If this foam product is not sensitive to its density (strength), then make it lighter (each material larger) would be more economical.
Hey, great Video! Could i bake my mold in a oven if i premoisture my eps beads? Thx, Cheers
Where do you get these beads?
Hey there, Where are you purchasing the beads from?
Tpp
Just the video I was looking for, thanks. Where do you purchase the pre expanded beads?
Hello sir. Can you tell me if there should be a hole in the mold so that the water can go in?
I think Zach put a hole in his mold in order to release the pressure.
@@EPSEPP Thank you)
Very good work
Thank you. very useful.
Thanks 🙏
I wonder how much outward pressure they exert when they expand. Could you make the mold out of plastic?
It depends on various parameters, In my working place, our maximum pressure "inside" mold is about 1.5 bar. As for plastic mold, I don't think they can handle the pressure & heat/cooling multiple times.
@@MultiKumar321 Usually when you buy those raw material, the provider tells you the density range. There are also phrase of pre-expand and aging before block molding, so there is lots to do actually "control the density". Some extreme case, even when you completed foaming, some clients use hydraulic press to compress and make the block's density higher. Please describe more specific phrase of density you are looking for.
@@MultiKumar321 We usually use steam as it is most efficient way in mass production, not hot water. If only in small amount, and not density sensitive, (because you are impressible control pressure inside dry oven), then it could be expand. I had never try this before. Beware that you are not possible to expand them and not 'shape' them by 'dry oven' way, you need stirring to prevent them from getting together.
Would this be suitable up 100 degrees, as insulation around hot water pipes in a car angine bay?
Is that a homework question? It would depend on the thermal properties of the specific type of polystyrene / foaming beads used 🤔
Not a school homework question. Just considering ways to insulate/keep hot waste vegetable oil, passing through filters on its way to the engine injection pump, which is better if the oil is gotten radiator temp hot!
Considering a copper coil tightly wrapped around a CAV oil filter cartridge and then encapsulated with foam of some sort to insulate it more!
Hi Zach, thank you for posting this video. it's really neat. We liked the setup that is shown in the video, especially the rotational molder machine. we are also looking for one in our lab. we would really appreciate your help if you could share a little info on the machine and its source
