We thoroughly enjoyed the visit from Sub-Zero who delivered us not only ice cream but also an educational, experience experimenting with liquid nitrogen.
We had a taste of our upcoming unit--states of matter, literally. Compliments to a gracious and generous parent, Sub-Zero, an ice cream vendor, who came to us and gave us hands-on experiments of the effects of nitrogen on solids (gummy bears, a rose, slick desks, and his hands) and water (itself) and gas (air in a balloon). The experience was a blast, literally, as well. We had balloons pop and ice cream tantalize not only our taste buds but also our brain cells as we watched it being made right before our eyes with nitrogen.
