This is SUPER easy for children and adults of all ages. All you need is plastic beads (I used pony beads) and a muffin tin. Preheat the oven to 400. Line the bottom of your muffin tin with one layer of beads. (Make sure you have some clear beads in the mix to let the light shine through). Bake in the oven for 20 to 25 minutes. Let cool. Flip over the tin into a plate, they should pop right out.
Obviously kids shouldn't work the oven or touch the hot pan, but they had a great time picking out the colors and lining the pan. Here are some of the color combos we came up with:
Note the black and gold one. Steelers nation, yeah!
After you extract your sun catchers from the pans, you need to drill a hole (again, adult's job) for the string.
There you have it! Go catch some sun :)
