This document provides instructions for creating a tornado in a bottle using water, glitter, a toy person, liquid soap, and two plastic bottles. The method involves placing the glitter and toy in one bottle with some water, adding soap, capping it with the second bottle, and quickly shaking it to generate a swirling tornado-like vortex between the bottles. The science explanation is that differing air temperatures cause the warm and cool air to spin upon colliding and form a tornado-like funnel.

1. How to make a tornado in a bottles
Aim:
To make the water turn into a tornadoes.
Materials:
1 drop liquid soap
1.5L water
2 x 2L bottles
1 toy person
glitter
sticky tape
Method:
1. Put water in 1 bottle (up to halfway).
2. Put glitter in the bottle where the water is.
3. Put the person in the bottle where the glitter is.
4. Put the soap in the bottle where the person is.
5. Pickup the bottle without the water and put it on the top
of the water bottle.
6. Tape around the bottles with sticky tape.
7. Turn around and quickly shake it.
And there you have it – a tornado!
The Science Behind It
First, the warm air and cool air are going in opposite ways.
Then, they crash together and start spinning. Then it gets
pulled into the cloud. Next, it turns from horizontal into
vertical. After that, it is so strong, it can pick up a truck, pick up
a tree and a house.A tornadolastsabout 10, 15 or even a 20
minutes.
