Efficient Paper Gliders.

Paper gliders would be a better, more accurate term to describe colloquial paper airplanes because they really just glide and nothing else.

In search of a perfect efficient paper glider, just to amuse lil' Adam, I found out 2 models that work pretty well.

1. "Swallow" form (http://www.zurqui.co.cr/crinfocus/paper/airplane.html)
2. " OmniWing " glider (http://www.omniwing.com/)

The first glider is interesting because you can modify it much like a remote controlled plane by tearing off edges to make rudders or bending the tail like a rudder to effect horizontal or vertical changes. The distance it can cover is slightly better than average paper planes. It would seldom spiral or head straight for the ground unless the wing is uneven and the fuselage's not straight.
A little bent in the tail can dictate whether it dives or climbs or climb & stall.

The second one which I just found and made is real neat. A little push and this baby can glide gracefully in a smooth descend. I asked my dad to try but he gripped it a little too hard causing the wings to become uneven. Then I asked my mum to toss it out of my house while I go downstairs to catch it. Sadly, due to the uneven wings, it spiralled and got stuck on the roof of some other structures. But nice spiral. Haha.

Give it a try, it's fun!
