Last month Olivia had a sleepover with two of her cousins, both of whom are very active. We wanted to do something outdoors that would be fun for all ages. I came across this idea on pinterest.
It's very simple, but lots of fun. We made marshmallow shooters out of a disposable cup and a balloon, both of which I had left over from Olivia's birthday party. I did find that the smaller the cup, the more accurate it shoots.
For a great tutorial on how to make them, check out this blog.
At night, we had a war and in the morning we used the launchers for a distance competition (who can shoot their marshmallow the farthest). They had a great time.
This could easily be adapted for indoors using pom-poms (as the original post suggests).
This was a little hard for my just turned 4 year old to operate, but it was definitely age appropriate for her 6 and 10 year old cousins - and her parents :)
Let the wars begin!
