We made the body out of furniture (cushion) foam, and covered it with latex. We started by painting latex out on plexiglass and using a hairdryer to dry quick. We kept it all very thin to keep the movement where we wanted it. We then painted latex over the whole thing to seal it. The video has an empty tank, we did this for our district show, but filled with water when it came back to our shop. We filled the tank with a mixture of water and antifreeze. That combination had produced some very cool "skin flakes" that get stirred up when it begins to move. We have the bug movement on a switch, so that we can have it moving or static. Bought a very cool DJ water light projector off of Amazon for like $8, that is how we got the changing color effect.
We got the cylinder from Pat Catans (craft store) for $26.00. We wanted to use clear PVC, but the cheapest I could find was $345.00 a foot
Got our inspiration from this:
