Age group(s) for this birthday party activity:
Elementary School

Cost of birthday party activity:
The slime kit costs about $25. It includes all supplies for 14 guests, and has enough stuff for 4 experiments.

Birthday party planning information:
The instuctions for the experiments are included. You will need a clear place for the "scientists" to work. I used aprons for each guest.

Other suggestions or comments:
The kids get to take their experiments home with them as a party favor. They can make slime, put it in a zipper bag, and have a souvenir!
