Summer and Claira were doing a drop test with foam and their phones inside the bin . They wanted to see what areas were weak. Once they found it out, then they could transport fossils with the bin to a lab, hypothetically. They can see how fragile fossils are when they are being tossed around in a bin in the back of a truck. The Dino-Mights are interested in this whole drop test experiment because they want to see how they can get fossils to the lab without harming or damaging the fossils at all.
