Hovercraft experiment

Last night we decided to try making a hovercraft. All you need are a balloon, a CD/DVD disc that you no longer need, the pop up lid of either a water bottle or dish soap bottle and some strong glue. Glue the lid in the centre of the disc. I used hot glue which worked perfectly and dries fast. Blow up a balloon and attach it to the closed lid. Be sure to attach the entire neck right to where the balloon becomes round - all the while keeping the air in the balloon (I twisted the 'neck' a few times). When the balloon is fully in place, pop the lid into the open position and see what happens. We had some successes and some failures as you can see...




Balloon was way too small




Balloon wasn't attached well enough




Balloon still not attached well enough



Not enough surface area





Still not enough surface area




Just right : )

Tonight we will try it in the bath and see what happens.
