Popsicles and Icicles

     Did we ever have a lot of fun today. We started the day with science, it's always going to be a great day when it starts with science. Yesterday we discovered what a penguin feels in the water when it's insulated by it's feathers and blubber. They stay really warm. Pictures will follow.
     We were wondering what would happen if a liquid wasn't insulated by blubber and feathers. As it turns out the liquid freezes. It just so happened to freeze into a tasty popsicle that we ate in the afternoon. One thing we found very interesting was that it only took 2 hours for our liquid to freeze. We were wondering if a liquid in a smaller container freezes faster than a liquid in a larger container?
     Our teacher, Ms. Brown wanted to also get us to try making icicles. We filled a large juice container with water, poured in food color (for effect) and hung it outside. She also poked a hole in it to have the water trickle out slowly. We're seeing if the water that trickles out will freeze into an icicle. It hasn't worked so far but we think it's because it warmed up here. We're going to leave it over night and see what happens. We'll keep you posted with pictures.

At the end of the day it looked the same. Something doesn't seem right. Perhaps if we leave it over night we will see some icicles forming. Does the size of the whole make a difference? Is it not cold enough? Why won't it work?
