Introduction: The Better Cd Hovercraft
self propelled. no push needed yay!
the reason i made this is because i was just looking around instructables and i saw CD hovercrafts but none were self propelled so... here u go
Step 1: What Is to Be Needed
what you will need for this is:
tape(doesn't matter what kind)
hot glue stick
PVC pipe (i used 1/2 inch flexible= easy to cut
ink tube of a pen
something to poke holes with
Step 2: Get to Pokin the Wholes
2 hole are needed
one is in the TOP of the bottle cap and the second hole is needed in the side
the hole in the side of the bottle cap need to be big enough for the ink tube(after emptied, this is important because, if this vital step is overlooked it r gone b a big mess!!!) to be a snug fit. no larger, no smaller
also insert the pipe in the centre of the cap so the hole is visible and mark where the ink tube comes through the side of the bottle cap then poke another hole in the side of the pipe to create a snug fit for the ink tube.
Step 3: Gluin Time
next glue the bottle cap on the compact disc
then place the pipe and the ink tube in place
make sure that an airtight seal is created so the only places where the air is escaping is out the ink tube and the bottom of the craft!
Step 4: Let It Loose Yo
the final step is to inflate the balloon and put it on the pipe and release
