Powerade powder

Today was my 3rd ride of the year and I went to store to get some sports drinks, and I found this one.

It's Powerade in powder form. Do you see what it says on the label?
"MAKES 2 GALLONS"
2 Gallons? 2?

The regular type was on sale and it was a dollar each. For that powder I paid $4, and I can make 2 gallons of that magical blue liquid.

I tested it today, and it tasted and worked just like the regular one.

From now one I think I'll buy powders and add water to it.
