Milk Plastic? Will it Work!

For Topic this week, we are learning about "Changes in Matter". We had to identify the difference between Physical and Chemical change. After we went and learned about it there were experiments that we got to choose from that you can do with HOUSEHOLD items. I decided to do Milk Plastic Tags.
This is how mine went...

That is when I first put one cup of milk into the glass.

This is when I put it in the microwave for 2 minutes.

After adding the vinegar in and mixing a tiny bit.

After mixing for a minute.

This is after straining.

These is all the colours I wanted to make my plastic.

I added my mixture into the colours and mixed (I only used the yellow in the end.)

And Done!!!!! Now I have to wait 2 or more days for it to dry!
