Day 12

we test the gun and evaluated what was wrong.the sealing tape was hurting the Cement. the power point was worked on. we finalized everything

day 9

we cut the valve holes in and put the vale in. we then put PVC cement to connect the air chamber to the barrel.

day 8

we began to build the t shirt launcher with a 2' barrel.we cut the PVC to the size needed to use as the air chamber. we also cut the barrel down to 2 ft to make it more portable. we used PVC cement to glue the  PVC top to one side of the air chamber. we hooked up the valve to the PVC to release the air.

day 7

day 5

i sketched up designs of possible prototypes. i also researched smaller cannons with less PVC. materials was look at to see what we could use as the barrel and chamber.

day 4

we revised our research paper and formatted it right. i added additional information to the history and included the bio of tshirtgun.com who is known in the field of t shirt launchers. they have been making pneumatic pressure cannons since 1991. i created a bibliography for the paper
