DIY Screamer Fireworks
Like Duolingo, but for DIY Screamer Fireworks. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
21 levels across 4 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through The First Launch, Making it Scream, Flight and Multi-Stage Mechanics, and Launch and Safety. It starts from scratch.

Key ideas in DIY Screamer Fireworks
- Paper is light enough for the small amount of fuel to lift it
- A smaller hole increases internal pressure for more thrust
- Tightly rolled paper is strong enough to contain the pressure without bursting
- A hole that is too wide lets gas escape too easily, resulting in no lift
- Heavy materials like metal create dangerous shrapnel if the motor fails
- A hole that is too small can cause the rocket to explode from over-pressurization
- Why paper is the preferred material for a screamer rocket body
- The relationship between nozzle size and rocket performance
- Bentite or kitty litter clay creates a rock-hard seal when compressed
- Air pockets or wrinkles cause the fuel to burn unevenly
- The plug prevents the fire from blowing out the back of the tube
- A smooth surface ensures the fuel 'grain' is solid and consistent
- Clay is non-flammable and won't catch fire during the burn
- Using the same diameter tool ensures the fuel volume is identical every time
- The function of the clay plug in a screamer motor
- Consistent tube length keeps the weight and balance predictable
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives DIY Screamer Fireworks the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
When ye shrink the size of the nozzle hole, what happens to the pressure inside the hull?
