Red iron oxide results in more noise, while Copper Oxychloride gives you more power.
Because the fuel is so powerful, they do require some special handling. You cannot make them the same way you do the more forgiving black powder rockets.
Do not EVER attempt hand-ram whistle rockets using a mallet. Do not attempt to drill into them.
Doing either can cause a catastrophic explosion.
You do not make them the same way you do the more forgiving black powder rockets. The rocket fuel used in these babies is a powerful explosive.
So, before you jump into the world of whistle rockets, there are a couple of things you’re gonna need:
- Knowledge - You need to know how to safely make whistle fuel, how to press the fuel into the tubes (and how NOT to). If you’re new to whistles, first read the tutorial from Ned Gorski on our whistle tool set pages.
- A Rocket Press - You cain’t whack whistle mix. You cannot ram whistle mix like you can black powder. Well, to be honest, you actually can whack it once, but not everybody gets a second chance. Instead of hammering whistle into tubes, you must use a press. And for your first press, you can easily modify an inexpensive arbor press. Just use Ned Gorski’s brand new project for making an arbor rocket press on our whistle tool set pages.
- Whistle Tooling - You HAVE to use tools to make whistles. You cannot drill into whistle mix, as you can with black powder. Skylighter’s professional grade whistle rocket tool sets include an aluminum base, hollow rammer, & solid rammer, and a stainless spindle. You can get your own set of tools here.
- Whistle fuel - There are different formulas out there for making whistle rockets. Don’t worry, you can find instructions for safely making whistle mix on our whistle toolset pages.
