Kid's Popsicle Art- would be a cool way to make a piece of art! It might also be fun on the last week of school. I could fit in the kids' lunch sticks!
I've already tried this and it's pretty cool!
Make a mailable slice of cake.....this is very cool! And funny!! People rarely take time to do really special things they send the quickest text or email whichever is most convenient or free. Someone made this and bought postage!! Wow!
