Kia ora everyone, it's Maori Language week. But that's not what I'm posting about today (I probably will later in the week). Today, we had a science show in the hall, which came from Australia.

| Get this off me! |
We learnt lots, and I think that was the point. For example, did you know that water is the only known substance (at normal air pressure) that can be liquid (water), solid (ice), and gas (water vapour)? We also learnt quite a bit about mixing colours.
 |
| Mix green, blue, and red together and you get brown. Ew! It even tasted horrible, according to the critics. |
They made huge bubbles that could probably fit a TV inside, as well as showing us rockets that use headache tablets and fly off unexpectedly.
 |
| This hairdryer could blow you all away! |

| You can make a ball fly if you put it above a hairdryer. |
Interesting fact: Polymers turn liquids into solids. We also learnt how nappies work. If you don't want to know, then skip 5 lines ahead. Ok, here goes.
Nappies work by absorbing liquids. For example, if you pour water onto a nappy, then it will absorb it. But how does that work? Polymers absorb. They put a powder of it in between the layers on the nappy, then it absorbs what the baby does. The nappy only needs to be changed when all the powder has been used.

| Add headache tablets to this and it flies off! |
Did you know that bubbles are the thinnest thing visible with the human eye?
Yet another thing we learnt about was friction. When you click your fingers (or tongue), you create friction which, in this case, makes noise. When you rub your hands together, you make friction which this time makes heat.

| Don't blink, and don't take your eyes off me! |
If you want to know how to decode the gibberish that they talk about on the weather report (a.k.a. low pressure and high pressure) then keep reading. Low pressure means wind, so you can probably guess what high pressure means. It means sun! Yay! My favourite thing that we saw was probably when they made the absolutely huge bubbles. The funniest time was when he kept telling us to not blink. The oddest thing that happened was when he set fire to some grains and they flew up in the air like fireworks. And now, for who was who. "He" was Richard. You may have noticed that there was someone sitting behind a computer as well. Her name was Robyn, and she was in charge of the music. Ms Sands and Mr Riceman took the photos. If you want to comment, then go ahead! Bye!
