Today at school we had a science show made by some scientists called Richard and Robin.
They showed us what you need to make fire... you need heat, oxygen and fuel. For fuel you could use different types of fuel like wood, paper and plastic.
Another thing they showed us was about bubbles. We learnt that bubbles are the thinnest thing you can see with just your eye. Richard blew a really big bubble about the size of 3 soccer balls. He also told us that bubbles have two layers and why. He said bubbles have 2 layers because the outside layer makes a reflection that's why balloons are multi coloured and the other layer inside the outside layer traps the water inside. Here are some videos.
We also learnt about physics. Richard had a hair dryer and a ping pong ball. Richard turned on the hair dryer then pointed it to the roof then put the ping pong ball by the hair dryer then he asked us to put our hands up if you thought the ball would fly up or if it would just hover. Then he let go of the ball and it started to hover because the air pushed it up and the gravity pulled it down.n Then he used a leaf blower and used a sphere with the world on it and it still hovered but it hit the roof . . . but it didn't matter because the ball was just made of air.
We also learnt about H2O which is water. We learnt that water is the only substance on earth that exists in Gas, Liquid and Solid. If you liked this blog post and you would like to get updated when I post follow me.Please feel free to comment.

Wow, that sounds like a really interesting show! I didn't know that bubbles were 2 layers, so I learned something new too 😊
