Eric did something really interesting with his InstaMorph. He used a hot, melted glob on the end of a straw and “blew” it as if it was molten glass. We asked him how he accoplished this…
“It was kinda trial-and-error — just take a smooth blob of melted InstaMorph and stick it to the end of a straw; then blow through the straw (hard!). It’s easier with less material or with extra-hot InstaMorph. The ball is thin and not really usable for anything other than as artwork — but that’s ok with me :) Thinking about putting a low-temp LED in there. The InstaMorph stuck to the straw, so using a metal or glass straw would probably fix that.”
You might be able to improve on Eric’s methods if you had a hot air gun that could keep the InstaMorph from cooling in its thinner state. Lot’s of fun possibilities here!
