I’m Ken Kuwako, a Science Trainer. Every day is an experiment!<\/strong><\/span><\/p>\n

Why doesn\u2019t a moving bicycle fall over? Why does a spinning top keep spinning without toppling over? The secret lies in something called the \u201cgyroscopic effect.\u201d The gyroscopic effect is the fascinating and rather mysterious property of a rotating object that makes it want to keep its axis of rotation pointing in the same direction.<\/p>\n

\u201cFor years, I\u2019ve wondered if there was an easy, homemade way to recreate and experience this fascinating phenomenon\u2026\u201d<\/p>\n

That thought had been sitting in the back of my mind for several years. Then, just the other day, I finally found the answer in the most unexpected place! It happened at Eiji Komori\u2019s training course for science experiment instructors. What he showed us looked, at first glance, like nothing more than an ordinary \u201cpaper cup rocket.\u201d Here\u2019s how to make one.<\/p>\n

What you\u2019ll need<\/h3>\n

Two paper cups, a pair of wire cutters, scissors, and one rubber band.<\/p>\n

Making the launch pad<\/h3>\n

First, make some cuts in the bottom of one of the paper cups. The bottom is fairly tough, so wire cutters work well for this.<\/p>\n

\"\"<\/p>\n

Next, use scissors to cut it as shown in the photo below.<\/p>\n

\"\"<\/p>\n

And that\u2019s it\u2014the launch pad is finished!<\/p>\n

Next, let\u2019s make the rocket. First, cut some slits into the second cup like this:<\/p>\n

\"\"<\/p>\n

Then stretch the rubber band across the cup in an X shape and hook it into the slits.<\/p>\n

\"\"<\/p>\n

That\u2019s all there is to it! Adding your own design makes it even more fun.<\/p>\n

\"\"<\/p>\n

It\u2019s incredibly easy to play with. Place the rocket on the launch pad and push it down from above. This stretches the rubber band.<\/p>\n

\"Paper<\/p>\n

\"Ready<\/p>\n

Let go, and off it goes!<\/p>\n
