Science experiment: Make a mini hovercraft

Friday, September 21, 2007

Ingredients

Cardboard disk Spool

Balloon Glue

Pencil

Instructions

STEP 1: Using a pencil, punch a hole in the middle of your cardboard disk.

STEP 2: Line up the hole in the middle of your cardboard disk with the hole in your spool. Glue the spool to the cardboard disc.

STEP 3: Stretch a balloon over the top of the spool.

STEP 4: Blow up your balloon and twist the end of the balloon closest to the spool to keep the air in the balloon.

STEP 5: While pinching the balloon closed, place the disc on a smooth surface and let go.

Explanation

Your hovercraft glides across the table because it's floating on a cushion of air. The air lifts the cardboard disc up creating less friction.

KFVS12 and the Southeast Missourian are teaming up for science. Every Tuesday you'll find an experiment from the KFVS Heartland Science Lab in the Class of 2morrow section of the Southeast Missourian. Grab the ingredients and join KFVS science reporter Jason Lindsey live on KFVS at 5 p.m. every Wednesday. More science experiences can be found at www.kfvs12.com and www.semissourian.com.
