Make An Air Bazooka

Despite its military title, there is nothing violent or destructive a good air bazooka. The environment bazooka or "airzooka" shoots a harmless puff of air using a flexible membrane to push it of the hole. This air burst travels remarkably far a properly built air bazooka can released a candle from 20 ft away and send naive felines bolting from over the room.

Instructions

1. Look for a box about 1 feet square. It ought to be open at the very top and closed at the end.

2. Fold all flaps around the open finish inward so that they are flush from the sides from the box.

3. Cut a 6-inch-diameter hole within the closed finish having a craft knife.

4. Reinforce the perimeters from the hole with duct tape in which the outer flaps from the bottom meet. This can avoid the flaps from coming apart.

5. Create a mix from two 5-inch strips of duct tape on the center of an unopened trash bag. Create a second X overlapping the very first but offset 45 levels. The 2 Xs need to look as an asterisk together.

6. Switch the bag over making another duct tape asterisk directly over the first.

7. Lay the bag flat within the open the surface of the box to ensure that the asterisk is in the actual middle. Press the bag lower to ensure that it sags about 4 inches in to the box in the center.

8. Tape the bag towards the outdoors from the box with duct tape. Tape completely around to produce an airtight seal.

9. Achieve in to the box and thread a screw hook through the middle of the tape asterisk. Screw it right into a small block of wood about 1 " across. The wood block ought to be outdoors this area in the heart of the asterisk.

10. Cut a little slit within the side from the box, about 5 inches lower in the top in the center of one for reds. Cut another slit in the center of the other side.

11. Place a small bit of dowel (2-3 inches long) through the middle of a sizable rubberband. Thread the rubberband with the slit therefore the dowel is from the outdoors from the box, held there through the tension from the rubberband.

12. Thread the band through the 2nd slit and around another small dowel. It ought to be extended trained across the center of this area.

13. Hook the screw hook around the rubberband. Put a bit of hiding tape over each dowel to carry them in position, and seal the slits to prevent air from seeping.

14. Withdraw around the wooden block and release it. The rubberband will pull it lower, delivering a jet of air from the hole towards the bottom from the box for many yards.
