Try this out on a St Patrick's Day gathering.
And see how your friends enjoy this.
Ask an adult to get you some of yellow as well as blue food colorings.
Preserve them in separate containers beforehand.
Take two clear cups of water, and a larger empty crystal glass.
Now serve one of your friends with a drop of yellow food coloring, and one empty cup.
Then it's time to make a yellow solution with drinking water by stirring the mixture thoroughly.
Now ask another to prepare a blue color solution the same way.
When both are ready it's your turn. Come forward with a large empty glass that can hold contents of both the glass. Then empty the two filled glasses into yours.
And see the magic.
Don't forget to add sugar before serving them to your friends.
A great toast for the Day!
