How to make
The first 3 products needed to make the rainbow shots need to be in a 1:1:1 ratio. Pour the prepared syrup into the bottom of a small glass.
Then, very carefully, pour the orange juice in a thin trickle with the orange right next to the edge of the glass (with a knife to help).
For the 3rd layer, use lemonade, pouring it in small trickle also. Decorate the shots with slices of lime or lemon.
