REALLY easy took me only 5 mins from household stuff :) you'll need a
CD
water bottle that has the pull to open top
ballon
glue ( hot gun or elmers glue i use hot glue gun)
and you need only 5 minutes :)

Step 1: Take the Cap Off the Bottle

remove the cap from the bottle

Step 2: The Cap and the CD

simply get the cap and the CD (use a CD thats not working) place the cap on the bottle like below (must be in the middle over the hole in the CD)

Step 3: Glue It On

glue the cap on the CD

Step 4: Finishing It Up

make sure there are no air leaks where you glued then blow up a ballon and put it on the cap (make sure the cap is shut so no air can escape)

Step 5: Video

when you are done pull the cap up and give it a good push (push it on a flat surface the flatter the better) heres a video
