Looking at the forecast for the weekend, I went surfing and found a list of things to do on a rainy day. This one caught my eye:

Hold a Mini-Marshmallow Popping Contest
What You Need
* scissors
* utility knife
* markers
* ruler
* rubber bands
* glue
* tape (transparent, duct, masking, or colored)
* gift wrap or decorative paper
* kraft paper
* balloon, uninflated (1 per popper)
* paper cup, bottom cut off (1 per popper)
* mini marshmallows
What to Do
1. Knot the end of the balloon, then snip off ½ inch from the top.
2. Stretch the balloon over the cutoff end of the cup so that the knot is in the center. (You’ll need to hold the balloon in place when you “pop,” or secure it with a rubber band for little hands.)
3. Place a mini marshmallow into the cup so it fits snugly in the knotted center of the balloon. While aiming the cup away from you (and others), pull the knot back, release, and send the marshmallow soaring. See who can pop marshmallows the farthest or get the most into a bowl that’s a few feet away.
