Today I am going to show you two instruments to predict the weather.

2
00:00:10,970 --> 00:00:16,969
This is a homemade thermometer.

3
00:00:16,969 --> 00:00:41,409
When you heat the water with the dryer, the water goes up in the straw, and when it goes, it goes down. Almost magic!

4
00:00:41,409 --> 00:01:09,370
This is an anemometer. It measures the speed of the wind.

5
00:01:09,370 --> 00:01:22,370
This is a weather band and measures the wind direction. Let's try it.

Thank you.
