Amazing science experiment!!!

                        Have you ever done a Tornado experiment with only 4 things?

Well, guess what Kea did! On Monday kea did a science experiment about tornados first we had to get into our groups Whaea Sam said to get into groups of four, two girls and two boys.

First Manu and I got into a pair and searched for two boys to join us. Then Manu saw her brother Nafi paired up with Ken and told them to join us so we could be a group.

Next Whaea Sam told us to come with her to Waka Toru, some other groups came as well.

After that, we got a 1.5-liter bottle and sat down at a table. Then we had to tip some water out or it wouldn't form a tornado. Then, we waited for Whaea Sam to finish with the other group so she could come to us. When Whaea Sam came to us she added pinkish-red food colouring and glitter.

A little while later we got to test our  Tornado. We had to shake it then count how long it would take to stop spinning. When we started the shaking Ken's brother Ha'amonga joined our group. Ken had the first turn shaking, his time was 10 seconds, Nafi got the same time, Ha'amonga was up next and got eight seconds, then Manu got two seconds and I got four seconds. Since Ken and Nafi got the most and tied they battled each other to see who could get the final score of longest spinning tornado Nafi won eventually because Ken got ten and Nafi got eleven. 

Finally, we wrote down what we noticed and recognized. We all noticed that when we shook the bottle, it formed a little tornado and we recognized that the glitter followed the water in a circle, which made it easier to see the tornado.

I wonder what would happen if we used two bottles like this photo
