Field Trip!

Yesterday My group and I went to this field trip to BPPT. It was only for our group. We learned heaps of thing s over there. We didn't even know if they could even can make rain. They would use an aeroplane and 1 tonne of soft salt to put in the clouds. They would go under clouds to see if it had enough air pressure. If the clouds had enough air pressure they would turn around and shoot out the 1 tonne of salt.

Try this:
Materials needed:
- A bowl full of salt
-Bowl (2)
-water
Step 1:
Pour the salt into a bowl.
Step2:
Pour the water into a bowl.
Step3:
Put the filled bowls next to each other. Leave them there for a night.
Step 4:
See the result the next morning. Part of the water from the bowl is gone and the salt in the bowl is sort of wet.
