First, we made snow. The videos I found online related to this experiment showed people taking a pot of boiling water outside and throwing it in the air. But if you don't like to wait, (hey, I have young kids - they're impatient!) we found that filling a travel coffee mug with hot water from our Keurig worked just as well! Our family loved this experiment so much we tried it 3 more times! :)
Next, we tried to blow bubbles outside and watch them freeze. I've seen many pictures online of this and they look so neat! But... it was so windy here that the bubbles would pop before they had a chance to freeze. So instead I showed my kiddos (ages 8 and 5) how to make super big bubbles! I use this experiment at school (both when studying bubbles and as a visual for what air masses look like). Just mix a little bit of Dawn detergent with some warm water and you have instant bubble solution. Pour a bit of the solution into a shallow pan or plate (or right on the lab tables if you want your tables cleaned during the activity!) and then blow into it using a straw. You can see in the picture of my daughter that these bubbles can get really big!!
Finally, we froze food coloring and water inside balloons and made cool ice decorations to put outside! Put the food coloring in the balloon FIRST, then attach the balloon to the bathroom faucet and let the water fill it up as large as you want. Tie it off, set it outside for a few hours, then cut the balloons off and TA-DA! Cool ice decorations!

| Here's our water-filled balloons sitting outside to freeze. (Oh, and a bottle of pop to try another experiment...which might have worked had the bottle not been dropped when bringing it back inside!) |

Hopefully you can take advantage of some cold weather before spring to try these! We had so much fun!
