Science

Today I did science. We had to fill three plates with water and one with coke. In one plate with water we put a teaspoon of raro and in another one with water with a teaspoon of salt.We left one plain. We got another plate and filled it with coke. Then we put half a potato in each with the flat side down.Then we left it for half an hour.At quarter of an hour we checked the potato and the only difference was the smell.When half a hour was finished I checked it and the salt one was a bit squishy . The raro  one turned a bit yellow.The plain water didn't do much it just went a bit soggy like the others and the coke one turned brown and all the coke went flat.I found science interesting with all the changes.
