In a shallow plate or bowl, mix the water and dish soap until all dissolved.
Bring it outside, put on gloves then dip a cookie cutter into the mixture. Slowly lift up and watch the crystals form! It's best to do this on a cold day (Under 10 degrees F is fastest to see them form) and no wind.
You can dip it unlimited times!
Notes
When I did mine, it was 4 degrees F and took 5-15 seconds to form and pop! If it's warmer, you may want to consider setting it on a table and watching it through a window!
