This was something fun we did at Megan's birthday party! All the kids loved it and it was so easy to put together (and cheap!). First I cleaned out some baby food jars for each kid that was coming. These were the perfect size for them. Then I took salt and rubbed chalk on it until I got the color I wanted! I first tried rubbing the salt on wax paper which worked will but got a few holes...wasn't bad. Just make sure you do a little at a time, that way you get the maximum color.
Then with a little adult help the kids filled their jars with the different colors! I did pull out the funals but we ended up not using them. The kids just used spoons to scoop each color in.
Thanks Flax & Twine for the great idea! We had a blast!
