My friend would like to different variations of paper airplanes through different air types (so to speak). He needs to build a wind tunnel but he needs an easy to build one and cheap. (He's saving up for a long-bow NOT a wind tunnel). Any ideas?
Everybody worries about 'becoming' a jerk, but if you're a jerk to begin with, you don't have to worry about ever becoming one.

Wind tunnels can be simple or complicated. Even the simple ones can seem complicated and expensive to the beginner.
Right here on ScienceBuddies it shows you how to build a very good basic wind tunnel. Check it out...http://www.sciencebuddies.org/science-f ... -toc.shtml
However your buddy decides to approach this project, be sure to HAVE FUN WITH SCIENCE!
