Thursday

This thursday I made a checklist of what we had, didn't have, had figured out, needed to figure out, and places to call.  First we have the weather balloon, handwarmers, helium, iphone, and a flip.  We need the container and parachute now.  We will launch it from SDS, and depending on the wind patterns it will go 20-40 miles away.  We figured out what we will use in the ballon and where to call.  Today went pretty good for me

Balloon Car project

           David and I did this balloon project together.  Our balloon racer was made out of Cd's for the wheels, wine corks and skewards for the axels, and a big piece of bread for the body.  Our race car went 5 meters the first time and 6 meters a few times after that.  I think ours should get most creative.

Mass: 205 grams
