Now that the temperatures are getting down to -20'c at night we made our colourful Ice Balls again to decorate our deck railing. We did these last year and since there were so simple to make we did them again.
The trick we found to make these without making a big mess in your house is to first put 4 to 6 drops of food colour into the balloon and then fill it with water by stretching the end of the balloon over the end of a faucet, like when you fill water balloons but we used regular balloons. Make sure to hold on tight and not over fill. You'll figure out what's tight enough and full enough quickly! We then set them in the snow along our bench so the snow allowed the balloon to keep it's round shape for the most part. We let them sit outside like this for two days as the snow acts like insulation and the bottom freeze last while the top freezes quickly.
This morning I check to make sure they were frozen solid and them removed the balloons.
I like how they shine when the sun hits them.
