Do you have a shaker cup?
Yes it came with the starter pack
Okay, fill your cup up with cold water up to the 16oz line on the side of the cup. Then you'll open a packet and dump the whole thing into it. Now some people put ice in underneath and some on top of the fan that comes with the cup, but I don't think it really matters so just get a few ice cubes in there and shake it up for like 2-3 minutes and boom! you're good to go
