She was inspired by an incident, when Livi tore Violet's squishy, and we were googling which glue would work best. We found online that super glue can dissolve squishies - interesting!
For the project, Cora cut up a large squishy and used five types of glues to adhere the pieces together.
After letting them cure for 24 hours, she used a luggage scale to measure the force required to tear them back apart. A few didn't break - those were some strong glues!
She found that epoxy, super glue and wood glue worked the best - and the super glue did not dissolve the squishies, in her tests.

Cora came in first place in her grade!
Should we mention that she came in first, out of two entries?
Naahh!
(There were actually nearly 100 participants in the fair, mostly in the primary grades.)
