Today (AKA 11 September 2017) we had a science show in the hall. The show was held by Richard & Robyn. They started off with with three rings. The rings were connected and then taken apart. I'm not going to spoil so you have to guess what each of the tricks are. Then Richard (the main guy) did this trick with some fluffy red balls. He put them in his fingers and more balls appeared then he stuffed it down his shirt and vomited it back up again. And to be honest I don't actually know how this works. Then we had a rocket experiment. In order for this to work you had to have a canister with a push lid. You also need water, plate and antacid. Then you put it together squish the bottle of water and then the rocket will go.
A nappy experiment👶
Then we did the nappy experiment. So basically Richard told us to pretend that the cup of yellow water was a baby with pee in it, and the cup with the powder, a nappy. He then poured the water into the cup... Then the water became solid!!!!! Actually it was a more jelly sort of substance. How it worked is because of polymer. He tried to pour it on his head but it wouldn't come out!!!!
Fire!🔥
Then we had a experiment with fire. We had a look at what caused fire. Gas, heat and oxygen. It was so cool! Richard demonstrated afterwards. Then we had a little firework. Richard grabbed the fire and threw it in the air! Swish! A spark flew into the air. 🎇
Water...Different ones💧💦🍧
We also learned about the different types of water, solid, liquid and air. Solid being ice, liquid being water and air being vapour./steam.
Air, wind and so on🎈
Then we experimented with hair dryers and leaf blower. We learnt that shockingly when the leaf blower blows the toilet paper it is actually air molecules causing the toilet paper to move. We also put a ping pong ball on top of a hair dryer and it floats. If you put two it's harder. And if you put a toilet paper roll the air goes through so it doesn't float and if you out a ball through it it will bounce up high because of the pressure.
Bubbles...POP!💥
Then we had a look at bubbles. Most people won't think much about bubbles but, it is actually a very interesting topic. Bubbles are the thinnest things that humans can see with the naked eye. And it reflects a rainbow because of the particles in the air. It was cool when Richard made gigantic bubbles.
End/Reflection
Soon it was the end... but we did have a lot of fun though. My favourite part was the fireworks🎆 because, the toilet paper bit and the bubbles. Lots of the cool science tricks are illusional I think. I wonder what other interesting, wonderful and wacky topics there are that maybe I could work on when I get to Intermediate/High School.
Here are some photos and videos.
