For this day, I tried out making Magical Color-Changing Drinks. This is a really cute magic trick to wow students at a classroom party! It would also be great for holidays, such as Saint Patrick's day.
To make these color-changing drinks, you simply put a few drops of food coloring in the bottom of a cup (I used a solo cup) and let it dry (I left it overnight, I'm sure you only need to leave it a few minutes). Then, when you're ready to party, you put ice in the cups to hide the food coloring. Serve clear liquids (sprite, water, club soda) and giggle as your victims are wowed and amazed as their drink turns color before their eyes!
