Model Rocket Recovery Wadding
Whenever you launch a rocket, you need flame-resistant wadding inside to protect the parachute or streamer from being melted into a plastic wad. What wadding does is trap the burning particles from the rocket engine's ejection charge so they can't reach the parachute. It also provides some insulation for the parachute, so it is less likely to melt from the tremendous heat of the ejection charge.
Using this recovery wadding is easy. Take several sheets of the wadding, and individually crumple them up into loose balls. Then drop them into the rocket before you insert the parachute. You need only enough to fill the tube to a depth of 2-times-the-diameter. For a typical rocket, that is about 3 sheets of wadding.
Flame-Resistant - Wadding in NOT ordinary tissue paper. It is treated with a special chemical to make it resistant to fire, so it is hard to burn. When exposed to a flame, it chars instead of burning. This feature is what protects the parachute from melting.
Soft and springy - Because it is springy, it fills the tube easily, preventing burning particles from slipping past and hitting the parachute.
Cost Effective - It is cheap insurance to improve the odds that the parachute opens fully and the model lands softly. Plus, you'll get 75 sheets of wadding, enough for about 25 flights.
