Oh man. I would have LOVED this as a kid. Heck, I'd probably still like making a few of these crayon rocks (I've always been fascinated by materials and the various forms they can take). If there's some childlike wonder to entertain, either for yourself or, you know, for an actual child, then we have the craft project for you!
C'mon - admit it... you've tasted your Crayolas. And they taste like...well, the way they smell.
Not so with these edible crayons from fashion and food site Luxaire. The colors are just as bold, but the medium itself is totally edible.
Did you know that you can paint candles with crayons? Me either. The entire process is easier than you'd probably think!
