This 10-Day challenge requires you to embrace the wonderful world of food. Solve a food problem: like food that's too crummy or spills too easily or that needs a clever protection. Maybe you can come up with a smart way to make a CrunchLabs logo out of food, or build a device that makes cooking easier, or maybe engineer something to feed yourself.

As always, be safe and get a parent's permission before building. Once you've filmed it, work with your parents to share it with us!

Campers stay busy this summer with five different build challenges Mark Rober issues in camp videos. Mark Rober picks a winner for each camp challenge—they'll win a prize pack. At the end of summer, one lucky winner wins the grand prize: a Platinum Ticket to CrunchLabs and a spot in the final video with Mark.
