More explosives to the game would be really nice in future updates i mean its called powder toy for a reson also there havent been any explosive updates for long and i think the explosive part is the reson to play TPT and yes of couse the other electic and physics parts too but in base the explosives. 

So the elements that " I " personally would enjoy (some of them are maybe suggested already)

1. Different types of combine able powders for making color full fires ( like Bengalic fires or flares http://en.wikipedia.org/wiki/Flare ). And by adding for types of powders that lights their own way it also gets fireworks way more customizable and good for the pyrotechnic part.

Example names :

PART 1

 PART 2

There is also a need so just add some simple combines to the game just to make it more realistic.

So here some examples:

----- Not really and combination -----

Black powder should be added and can burn whit contact of wax like a fuse but in higher pressure it explodes like a bomb   Info :

Gunpowder, also known since the late 19th century as black powder, was the first chemical explosive and the only one known until the mid-1800s. It is a mixture of sulfur, charcoal, and potassium nitrate (saltpeter)—with the sulfur and charcoal acting as fuels, while the saltpetre works as an oxidizer.^[2] Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a pyrotechnic composition in fireworks.

Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently lowbrisance. Low explosives deflagrate (i.e., burn) at subsonic speeds, whereas high explosives detonate, producing asupersonic wave. Gunpowder's burning rate increases with pressure, so it will burst containers if contained but otherwise just burns in the open. Ignition of the powder packed behind a bullet must generate enough pressure to force it from the muzzle at high speed, but not enough to rupture the gun barrel..........

I Hope that will do it, and i really hope i see this soon becuse this is what makes people play or sry for saying bad of the technic and so part i really like that too but now is it time for some updates to the explosives 

// Pyropro

// Plz define what you meant whit "uses?"
