How to be safe in Science

Planning
Aim. I want to find out how to be safe in Science. 
Equipment: Bucket, 
Detergent, 
Gas, 
Tube,
 Cold water,
 Safety goggles,
 tap,
 gas tap,
 lighter.

Method:

1. Get a big bucket/box.
2. Get liquid soap/detergent and put in a good amount.
3. Fill bucket halfway with cold water.
4. Pull your sleeve's up, take off loose clothing , tie up your long hair- if you have long hair.
5. Make sure you have safety goggles and put them on!!
6. Connect the tube up to the gas tap, and then put the other end end of the tube in the water.
7. Turn on the gas and make some bubbles.
8. Wet your hands, wrist and forearm/ wet your hands up to your elbows.

Doing
 This is a photo of my friend Cole.
He says it "It smelt like a burning erosion of asparagus, and it felt like I was going to get burnt because  I had fire in front of my precious face. Then he talked about how it looked he said" it looked like a flame ball blow up."Cole then said"I could hear the flame ball explode."

Explaining
Why does hot air rise. Hot air rises because when you heat up air it expands when the air expands it becomes less dense then the air around it. The less dense hot air then floats in the more dense cold air like how wood floats on water because its less dense.

Why is gas flammable? flammable and combustible liquids do not burn themselves. It is the mixture of their vapors and air that burns. Gasoline, with a flashpoint of -40°C (-40°F), is a flammable liquid. Even at temperatures as low as -40°C (-40°F), it gives off enough vapour to form a burnable mixture in air.
