Here is a fun little experiment trying to see if sound effects how a bubble freezes. The first two bubbles are without sound for a control variable, and the second two are with the singing bowl being played. I am not certain if the sound makes a difference, mat need a larger test group! What do you think?
Bubble mix: 2 tbsp sugar mixed into 4 oz water + 2 tsp corn syrup + 2 tsp dish soap
The sugar makes the ice crystals more pronounced and the corn syrup is optional. The syrup makes them stronger and more wind resistant. You could substitute honey or waffle syrup 😁.
