If you are looking for some outdoor winter fun which also happens to be a very easy science experiment, this is for you and your children - Frozen Bubbles.
In order for bubbles to freeze, the temperature needs to be below 0 degrees Celsius (32 degrees Fahrenheit). In January and February very cold temperatures will work best.
To get the longest lasting frozen orbs, try blowing the bubble onto the ground, a tree branch or table. Make sure that you are shielded from the wind.
Be sure to have your camera ready to capture these amazing works of art in nature. When the sunlight catching through the bubble, you will see rainbows and so much more as they crystallize.
