DIY Fashion ♥ Toothbrush Bracelets

How cute are those?

It took me a while to get the different between thermoplastic and thermoset polymers down. Then I realized it's nothing but word origins.

• thermoplastic...thermo = heat...plastic = change shape...so thermoplastics are things that, when heated, change shape...
• thermoset...thermo = heat...set = not changing shape...so thermosets are things that, when heated, don't change shape...

Clearly, whatever cheap, pretty, translucent polymer these toothbrushes are made of are thermoplastic.

Now I just need to find the absolute cheapest way to buy a few hundred of these for my classes.

Thanks, by the way, to Jen Donaldson for sending in today's project video.
