You've got to try these balloons! Speaking from experience ... they are hilarious!
Simply blow up the balloon to its full length, then let it go. They fly about making noise for up to 10 seconds. It's a lot of fun watching or chasing them about. If you do this inside your house, they'll race about the ceiling and against the walls, occasionally flying through the room. If you do this outside, they'll zoom off into the sky, then fall to the ground.
Each pack contains 6 quality balloons with a couple of blow pipes. The colours vary so the image is indicative only.
Made in Taiwan where all good balloons are made!
