Let's try making a special glider with round wings. Can they can still take advantage of the Bernoulli principle and glide like a normal glider does?
What you'll need:
- Drinking Straw (around 20cm long)
- Make a loop out of each strip of paper. Overlap the ends with enough room to squeeze a straw through. Tape the ends
- Push the straw through the pockets in the loops. The large ring goes to the back and the small ring to the front.
- Launch the ring glider with a gentle flat throw.
Experiment with the position of the rings. Does it make any difference if you move the rings forward and back or change the order of the rings?
The round wings work in the same way as flatter wings. The air moves more slowly under the wing and the higher air pressure lifts the plane into the air.
Who can make the glider that flies the furtherest?
