Look at these images, and look long and hard. These are the consequences of accidents with explosives. Explosives are NOT a joke, and you run the risk of these accidents happening to you if you cut corners, use false information, rush things, don't want to learn the right way, don't wan't to learn full stop. Summing it up, LEARN AND PAY ATTENTION. Things are done the way they are for a reason. False information is dismissed for a reason. Things are deemed wreckless/dangerous/stupid for a reason, not just because we don't like the sound of it, because it is.
Here it is (taken from an outside site):
These could be YOU someday, should you fail to observe proper precautions when handling pyrotechnic and explosive compositions (these are the most severe WORST CASE scenarios but the intent here is to drive a point home).
Don't let the images get the better of your cautious side; by all means practice the art of pyrotechnics! Just do it safely.
This person was using black powder to assist in lighting a "Sparkler Fountain" on the 4th of July. What he did not know was that the fountain was smouldering. When the black powder exploded, it drove the container into his knee. The black cloth is where it drove his pants into his knee. He received several burns in addition to this injury.
This is what happens when a military simulator (M116) goes off accidentally. This person lost his thumb and part of his hand in the accident.
This child did not live long enough to discover that it is not wise to put explosives in your mouth. This injury was caused by a blasting cap.
This person was attempting to burn off the protective wax coating on the fuse of an M-80 type of firework. Injuries to the hands and face are the most common types of fireworks injuries.
A similar type of injury after the hand had been stitched up.
This is a photo of the left hand of an 18 yr old. His ring finger, little finger, and a portion of his palm were blown away when a pipe bomb exploded ( metal 6" x 3/4" in diameter). He was attempting to close the pipe bomb when it went off in his hand.
This is a photo of the left leg of a juvenile. The juvenile built a CO2 cartridge bomb by filling an empty CO2 cartridge with smoke bomb powder and fusing it with smoke bomb cannon fuse. When the juvenile lit the fuse, it was too short, exploding the bomb prematurely. A piece of shrapnel went all the way through his left leg and would have probably killed him if it had hit him in the torso.
This is a photo of the right hand of an injured adult. This occurred when a booby trap device exploded while he was placing it to protect his residential marijuana grow. The device was made from a plastic tube, 20ga shotgun round, and trip line.
This is second and third degree burns to a hand. It probably hurts less to have your hand blown off than it does to have it burned.
Fireworks burn at very high temperatures. If your hand gets too close to them while they are burning, you can expect your hand to look similar to this. The appearance does not even come close to showing how much it hurts.
This is what happens when a person tries to use a pipe bomb and it goes off while they are holding it. The pieces that could be found were placed back in approximately their correct location for this photograph. The head is at the bottom of the screen and the right foot is at the top of the screen.

Thanks to Shalshaska for digging up/finding the site.
Additional info from BurntAluminum:
Having your hand blown off indeed can hurt less than a burn, but it can also hurt more. In the case of 3rd degree burns they usually damage the nerves, and a lot of the flesh, thus removing feeling, however if in certain area's that the nerves weren't damaged in, they will hurt like a bitch.
