While searching for some good simple physics puzzles to help out my wife in her class quiz tomorrow… came across a site to build a pretty sophisticated looking paper aeroplane!
Remembered all the countless aeroplanes during school days – there were two categories – the gliding one, and a rocket that just went straight. My favorite was the gliding one, and with enough practice, one can find out how to make planes that glide for longer. Its also possible to learn how to throw a well made plane in such a way that it comes back to the thrower in an arc 8)
Click on the picture to see how to build it…
Got hopelessly distracted, but got back on track once I got stuck at step 18 🙁 [but will try again one more time later ;)]

Explaining the physics of everyday life – really good one but have to wade through them a lot to get to simple ones answerable by Pre University students! 🙂
When one bubble meets with another, the resulting union is always one of total sharing and compromise (Human beings could learn a lot from bubbles.) Since bubbles always try to minimize surface area two bubbles will merge to share a common wall.

Pure logical thinking cannot yield us any knowledge of the empirical world: all knowledge of reality starts from experience and ends in it. (Albert Einstein, 1954)
