Would Sandy’s Treedome Implode Under Bikini Bottom?

Who lives in a treedome under the sea? Sandy Cheeks does. But remember that the sea is very heavy. So if our favorite deep-diving land mammal’s treedome were under that kind of load, wouldn’t it quickly implode?

In the delightful cartoon Spongebob Squarepants, Sandy Cheeks is a squirrel from Texas that lives at the bottom of Bikini Bottom with the aid of a giant transparent dome, furnished with an oak tree, picnic table, and running wheel. It looks like a decent reverse-aquarium, but the lack of inhalable oxygen isn’t the only worry under the waves. If Sandy’s treedome isn’t strong enough, the crushing water pressure would cause an implosion not fit for a children’s show.

In my latest Because Science, we’re putting the pressure on Sandy’s structure to see if it stands up. We first have to know just how deep underwater her implodeable abode is, what its dimensions are, and what it’s made of. Once we have all of that, a few basic equations will tell us everything we need to know, and maybe some things we didn’t expect.
