That type of bike can really come in useful for the outdoor type of person :)
You can make your fast freeze experiment. What you need are: a bottle of very pure water, a fridge and very importantly patience. Freeze water to just below freezing, gently remove it. Give a smack and watch the "magic" ice form from top down :) If you don't get it in first try, don't worry maybe the 8th may just do the trick :)
