Prepare for lift off!

Today the green group met up with their grade 4 reading buddies to launch to rockets that they created last week. For fuel, we had a choice of Coke and Mentos, or Alka seltzer and water. After trying both fuel sources, we discovered that the alka seltzer tablet worked far better, allowing some of the rockets to launch quite high. Although we had discussed what attributes might make a good rocket (an aerodynamic tip, wings, etc), it seemed as if the simplest rockets worked best.

The tablet has mixed with the water, creating a chemical reaction, forcing the rocket into the air as the tablet starts fizzing.
