How To Build A Bottle Rocket And the parachute idea is good one for a smooth landing. The objective to achieve the highest time aloft for the ping pong ball. You can now tie the strings to the canopy. The launcher we will be constructing is a variation of the Clark Cable Tie launcher, as this is the most reliable launcher that is easy to make. If you launch at an angle the rocket will fly in an arc and it will be moving at considerable speed when the parachute deploys. If either one or even both of the parachutes became tangled or failed to inflate, the separate rocket sections would be too unstable to fall ballistically to the ground. It's simpler then it sounds to make a working bottle rocket and doesn't cost you much money. This image may not be used by other entities without the express written consent of wikiHow, Inc.
