In this video we use a high-speed video camera capable of recording up to 15 kfps to measure the muzzle velocity of a paper dart shot from blowgun. The darts were manufactured from 70 mm x 297 mm strips of 80 g/m² A4 printer paper. They are fast enough to penetrate a double-wall corrugated cardboard box from a distance of several meters.
Blowgun specifications:
* Stainless steel pipe
* Inside diameter: 14 mm (cal. 55)
* Wall thickness: 1 mm
* Lengths: 1 m and 2 m
