What You Need:
- A regular plastic drinking straw
- Index card or stiff paper - 3x5inches
- Cut the index card or stiff paper into 3 separate pieces that measure 2.5x13cms.
- Take 2 pieces of the paper and tape them together into a hoop as shown. Be sure to overlap the pieces about 1cm so that they keep a nice round shape once taped.
- Use the last strip of paper to make a smaller hoop, overlapping the edges a bit like before.
- Tape the paper loops to the ends of the straw as shown below. The straw should be lined up on the inside of the loops.
- Now hold the straw in the middle with the hoops on top and throw it in the air similar to how you might throw a dart angled slightly up. With some practise you can get it to go farther than many paper airplanes.
The two sizes of hoops help to keep the straw balanced as it flies. The big hoop creates drag (or air resistance) which helps keep the straw level while the smaller hoop at the front keeps the hoop glider from turning off course. Since objects of different weight generally fall at the same speed, the hoop will always remain upright!
