Balloon Racer

Doing the balloon car project was really fun.  I was with Ashley and it took us a ton of tries!  We first started off with a big car made out of styrofoam.  It had big cd wheels and a funnel coming out of the back.  We tested it and it of course did not work.  So, the next day Ashley brought in some cracker jack box's.  We thought that if we decreased the size of the car and wheels it would go faster.  This model also did not work!    Our third design was styrofoam, but with smaller wheels.  Our farthest ground covered was 12 square blocks.  We got in the bracket, but we lost to Elizabeth, Gray, and Lauren's car.  Although we built a ton of models, it was still a really cool project and I had a great time doing it.

The Journey of the Parachute...!

Our group (Gray, Elizabeth, Zelle, and Gabby) have accomplished a lot with the cute pink parachute! :)  We started off with making a ton of test parachutes and later on we made the real model.  The test were really fun though because we could see what we needed to fix or what needed to stay the same.  Around the second test parachute we decided to make the spill hole smaller and make the body of the parachute wider.  Once we made these adjustments it worked.  Then we had to wait for the real fabric to come in.  It took about a week or so for all the material to come in.  Once it was all in we made an outline on the chute with sharpie.  The group decided to cut it in a circle with a really small spill hole at the top.  At the very bottom we are sewing three steel rings on to four different sides of the chute.  This is where we will attach the strings/rope.  Once we are done sewing we will test the entire thing out.

Wednesday Class

Today our group did another test parachute.  We made the parachute shorter and wider, we also made a smaller spill hole.  Once the parachute was finished we attached Ashley, Lauren, and Aalia's container.  We went outside and it worked!  The parachute held the container and it landed safely.  We have the entire thing on tape, which i will add to the blog tomorrow...  It was really fun though:)
