The student's polymer project group wanted to make an iPhone speaker, but their polymers did not turn out as expected - one was hard as a rock, half of another was hard like paper, and the other half was still sticky. This prevented them from making the speaker. The student then went home and used the polymers to make an ISB magnet, cardholder, and hot pot/trivet. They decided to package these items together in a small ISB kit to sell.
