Can you freeze the playdough?

this reminds me of hollow tip bullets because it spreads out on impact but still with significant strength
I'll have to try this however my child hood play dough has dried out by now, have you considered drying the play dough in a mold
I got an Idea try adding playdough around a pointed projectile to improve areodynamics

Hollow point bullets are designed to expand (like a mushroom) in the target causeing massive tissue damage but not much penetration power compared to FMJ (full metal jaketed) bullets.

Of course just another fact not a suggestion for shooting living things.

Actually a friend and I are startin to experiment with harding it in 2" pvc molds using a small space heater and a lot of time. Its really cheap at any Target or Walmart. I think we got 4 cans for under 2 dollars. We are also thinking of making hollow shells for baby powder "morter" type projectiles.

No matter how rich you become, how famous or powerful, when you die the size of your funeral will still pretty much depend on the weather.

Ya, maybe when you shoot it and it hits something it explodes releasing flour or baby powder?


Discussion of solid propellants, explosive devices or incendiary projectiles fired specifically from a spud cannon is prohibited, and may result in a permanent banning of your account.For the purpose of this forum, these definitions will be used:
Solid propellant: Any substance containing all the chemical elements required to enable sustained combustion without the presence of additional oxidizers. This includes but is not limited to gunpowder, thermite, and many commercial and/or homemade pyrotechnic compounds.
For this purpose, nitroglycerine, though liquid, would qualify.
For this purpose, ordinary flour, though solid, would not qualify.

Zen, I don't think this qualifies as a solid propellant. Yes, talcum powder can be made to explode but his "explosion" is a little different. It is along the same lines as a potato "exploding" when it hits a hard object.

Exactly what we are going for. More a marker or a smoke screen affect.

But why did PC guy put it in as a example?
How can you use flour as a propelant?

Throw some flour on a fire and watch. Talcum powder, under the right conditions, can be made to do the same thing.

Maybe I misunderstood what you were saying. I took it as he is not allowed to talk about shooting baby powder from his launcher. Is that what it means? If not, I apologize.

with the right air to flour ratio it can sustain combustion but it would most likely never work. actually any dust like substance can sustain a flame but only under extremly special circumstances, meaning its incredably hard to ignite.

We are only using it to make a splatter on impact not an actual detonation or ignition.

Which is why it would be so cool. A video would be even cooler.

Living in wisconsin we grow a lot of corn and wheat around here and every once in a while you hear about grain silos exploding. that to is from dust particles mixed with the right combination of air and catching on fire. Usually from faulty wiring in elevator motors. Ends up making a huge mess and turns the silo almost inside out.
