Plastimake sounds like something you would have to pick up after your toy dog.

Non-toxic, biodegradable, clean, easy, AND fast, this stuff sounds as fictional, as futuristic as the Cicrert, except Plastimake is actually available for purchase! It might even replace Brookstone’s Kinetic Sand as my favorite toy (since that stuff is roughly as toxic as yellowcake uranium).

The stuff comes in hard white plastic pellets, but it becomes pliable and transparent at 140°F,  so you can work it with your bare hands while it’s still soft. When it cools, it forms (relatively) hard white plastic in whatever shape you’ve worked it. But here’s the kicker: you can always melt it again and make it into something else. Plastimake can be heated and reworked and cooled as many times as you like. That’s amazing. There’s no waste!

“All you need to get started is an idea, a bowl of hot water and your hands.”

People have been making some pretty trippy things with it, including costumes, toys, jewelry, and tools. They’ve been making repairs and improvements to everyday objects, and even invented things you didn’t know you need.
