"Air bombs", which are a kind of noisy Roman Candle, are going to be made illegal because they're so easy for young people to buy.
Air bombs cost between 20p and £1 and they caused about a fifth of all firework accidents last year.
'Bang goes your image'
On-the-spot fines for anyone over the age of 18 caught throwing fireworks in the street in four towns will also be introduced. If it's successful, it could be introduced around the country.
This year's slogan to try to stop young people playing with fireworks is "fool with fireworks and bang goes your image".
Loads of teenagers get hurt, and some are even killed, every bonfire night on 5 November.
