How to use a Meier shot ski:
1) Fill plastic ski boot to the appropriate level - green circle is 1 ounce, blue square is 2 ounces, black diamond is 3 ounces (plan accordingly)
2) Drink! Tall people, squat down to the same level as shortest person. Otherwise, said person gets the liquid all over their face/shirt/head.
3) Release the binding on the shot ski boot to wash. Or not. You do you.
