First: It's air conditioned. This is a big selling point, especially during the off-season (read: summer).
If you used disposable plastic containers, like Ziplock or what some brands of lunchmeat come in, you could have identical bins like that.
If you can make the pieces exactly equal, you'd be building in great math skills, for learning fractions.
The museum's setup includes a "real" brick pizza oven (with flickering red flames), and a cash register so your friends can pay for the pizza you made for them.
You have to pull yourself up on this chair.
This is awesome, you make a path for the ping pong ball to travel by inserting boards into the slats.
You can paint a real VW Beetle! This is less than half of the stuff there is to do there. They have crafts, and car building, and a huge dress-up room and all kinds of crazy stuff.
And maybe you'll get to see a real roadrunner, beep-beep-zip-BANG!
I'm not sure the age range of the museum, but Starboy's 8- and 9-year-old cousins had a ball. If you have elementary kids and are making a trip to Palm Springs, I really recommend the Children's museum as a getaway from your getaway, and a way to immerse yourself in play-based learning. It's really incredible.
