The Blowgun Demonstration Experiment
Tsukamoto, Koji; Uchino, Masanori
Physics Teacher, v46 n6 p334-336 Sep 2008
We have found that a simple demonstration experiment using a match or a cotton swab and a drinking straw or an acrylic pipe serves as an effective introduction to dynamics. The most basic apparatus has a cotton swab serving as a dart and the straw as the blowgun. When blown from a starting point near the exit end of the straw, the cotton swab does not fly a significant distance. When the starting point is closer to the lips, the straw is projected 2-3 m. If two or three straws are connected to form a longer blowgun, the cotton swab flies even farther.
