Fun With Ice Balloons
I have wanted to try making ice balloons ever since I pinned them on Pinterest but it hasn't really been cold enough in Brooklyn until last week. If you haven't seen ice balloons before, you can read the original post over at queenvanna.wordpress.com, hers are in a lovely rainbow array of colors .. we only had blue and green food coloring but we still had fun.
Put a few drops of food coloring in your balloon first and then stretch the lip of the balloon over the faucet and fill slowly like you are filling up a water balloon. After you tie off the balloon, shake it up a little to mix the color and then leave the balloons outside. We did this before going to bed - it took about 15 hours of 20 degree weather for the balloons to freeze all the way to the center. Once it is frozen, cut the balloon off with scissors and you have an ice balloon! Note: hands will get food coloring on them so you may want to do it on a bath night.
We started our experimentation in the sink but I soon realized we were going to waste way too much water so I moved her to the bathtub with a large bowl of water, a toy hammer, a toy screwdriver and a spoon and she had a great time hammering and watching little pieces melt. In the end, we left one in the water and one in the tub to see which would melt faster - she remembered to check on them every half hour without being reminded. In the end, it was a great way to kill some time on a super cold day. Let us know if you try it with your little ones and send us some pictures.
