I filled two bowls full for each of the little ones to play with during school time, but even the big kids were asking to play with them after they were all done with their work!
There is something strangely therapeutic about running your hands through popcorn kernels (seriously, you should try it)...Mommy enjoyed playing in it too! :)
Yes, it makes a mess, but we just sweep it up when we're all done...and like most fun things...The mess is usually worth it. :)
