These 33 Edible Science Projects Are Educational and Yummy, Too

Have your science experiments, and eat them too!

Collage of Edible Science Activities

Kitchen and food science are very popular these days, but not every experiment is fit to eat when you’re done. Fortunately, we’ve put together a menu of edible science activities you’ll be happy to snack on! Most of them are easy enough for anyone to tackle and can be completed with items you already have on hand. Bon appétit!

1. DIY Gummy Bears
