Note: "Mine" in pyrotechnics means "star mine", not "land mine". These are NOT made to explode when you step on them, they are made to shoot stars into the air when the fuse is lit.

The traditional way to make mines is to use sturdy cardboard tubes, but here is another way they can be made.

Materials:

Yogurt cup with lid (this is where the name comes from!)
Lift powder (blackpowder or similar)
Stars (made or taken from other fireworks)
Anything else you want to add (crackling balls, firecrackers, fuses)

Procedure:

1. Get your yogurt cup (without the lid on) and wrap it in duct tape. There isn't an exact number of wraps or anything, but give it a minimum of 5 layers (preferably more).
2. Drill a fuse hole (you can make your hole before wrapping, but this way you can control the size of the hole better and don't have to work around the fuse while taping).
3. Pour in lift powder, stars, and anything else.
4. Put lid on and tape. I use two "X" patterns of tape to seal the whole thing.
5. Light it! Make sure it is in an open area and you are a safe distance away in case it explodes!
