It's not for food.... it's for putting tumblers / cups on device so it can turn as you decorate it however you'd like... It's made with pvc pipe, metal and a pink paint ( spray paint ? ) coloring.... I am a bit confused as to why this would be used for food... I'm sorry and I hope this helps...

It's 110v has a normal US plug for electricity

I can’t answer if you’re looking for this EXACT epoxy, but you can find many options by searching “epoxy for tumblers”.

Yes it does. Turn it off and back on again after one second it’ll reverse direction.
