Make your own bioplastic

That's just goop.

I guess it's a plastic and all, but it looks like you're making a big blob of snot.

The recipe goes a little something like this...

• 1 tbsp cornstarch (tapioca starch recommended in the video)
• 4 tbsp water
• 1 tsp glycerine
• 1 tsp vinegar
• mix while cold
• heat until thick and snot-toothpaste-like and completely clear (see 1:50 for final product)
• spread on silicon mat and let cool

Here's another, similar recipe with way more explanation of the science - but a foolishly white background making the mixture almost impossible to see.
