Put your Glacier Ball in the freezer. Pro tip: to prevent your sphere from cracking, place the ball away from the cold air vent inside your freezer.
After few hours, remove your frozen crystal ball from the freezer and let it sit for 10 minutes at room temperature (this allows the ball to settle and prevents cracking).
Remove the top half of the mold, turn the ball upside down, loosen the bottom piece, and BOOM. Pour yourself a drink that'll stay good to the last drop (literally).
