Where Passion Meets Exploration

Freezing soap bubbles have been suggested as an analog for micrometeorite re-crystallization. In one example, a nickel-iron metal bead will trigger the crystallization and the crystallization will proceed backwards from the bead. This is similar to the formation of crystals from contact with the frozen ground. In a second example, when individual crystals (‘seeds’) start forming within the molten glass, triggering crystallization outward from each individual crystal ‘seed’. This may engulf the entire micrometeorite or form individual Olivine crystals around each crystal ‘seed’ within the glass that may inter-grow with each other. This is evident in freezing soap bubbles as well. Individual ‘seeds’ can be seen ‘riding the currents’ on the soap bubble as they trigger crystallization. Check out the images, GIFs and videos below for further examples and try it for yourself. Here is my current favorite solution:

· 40ml/parts warm water

· 7ml/parts corn syrup (Karo or similar)

· 7ml/parts dish soap

· ~6 ml/parts sugar

Remember, it must be very cold outside! I have had best results when the temperatures were well below zero Fahrenheit! I also recommend using a straw – it provides more control. I recently read that using a bottle to inflate the bubble rather than your mouth provides air that is closer to the outside temperature, so bubbles may not burst as readily – I will be trying that next time.

Enjoy!
