These are much more complicated than the ones I made years back.
They actually have fins and the bamboo skewer (slid inside the body wall) give it some guidance.

There are other videos with people tamping match heads into various containers - NOT A GOOD IDEA!
One match can strike and ignite another match head. The whole bundle could light and explode.
If you try this, stay with one match head and don't aim it at anything!
