Fun Experiment with Frozen Orbs

I saw this idea last year and was hoping to remember to do it with our great nieces this year.  You put some food coloring in a balloon (use bigger balloons - these are kind of small), put the opening of the balloon on the end of your faucet and fill with water.  Tie and then shake gently and put outside (or in your freezer) to freeze.  It takes quite a while to totally freeze them.  Like longer than overnight in 0 degrees.

When totally frozen, and with rubber gloves on, snip the balloon with scissors or a knife and peel the balloon off.  It comes off very easy.  If doing several colors, you'll need to rinse your gloves in between colors because the food coloring will get on your gloves and transfer to the next color.  You see some blue on my yellow one.

Most winters if we have snow it stays white everywhere all winter.  (I was used to it melting between snows in Indiana)  So I really like it that these will be colorful decorations in the snow by our front sidewalk all winter!  My favorite is the dark blue one and the yellow one on the right in the front.

I have a couple more out there that still have the balloons on.  I think one may be purple because the girls wanted to mix red and blue to try to make a purple one.  They thought it was fun. 

It will be fun to see how long we have them.  April?  Anyone want to guess?  Leave your guess in the comments below.
