How do you make a homemade rocket fly?

All you need is baking soda, vinegar, a paper towel, three pencils, some tape, and a plastic soda bottle. This basic chemical reaction can launch the rocket up to 100 feet. The more backing soda and vinegar you use, the greater the thrust capacity.

Does the size of the parachute matter?

How large a parachute is (in other words, the parachute’s surface area) affects its air resistance, or drag force. The larger the parachute, the greater the drag force. In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.

Do parachutes have a weight limit?

Why Is There a Weight Limit for Tandem Skydiving? In a word, safety. Tandem parachutes are built for two people and these parachutes come with safety recommendations for maximum suspended weight – usually, 500lbs which includes two persons plus gear.
