This is such a simple cocktail you can make for kids of all ages. All you do is take glasses, fill to the top with ice. Next pour in your favorite lemon/lime soda. Then fill a syringe with grenadine, squeeze a little in the drink. It's just a Shirley Temple but by putting the grenadine filled syringe it makes it look like you're squeezing blood in. You could also make an "adult" version if you'd like, by adding cherry vodka.

So simple!
