get yourself a 2 litre plastic jug, run tap till its hot, put 2 scoops in and then hold under hot water tap and give it a swirl, best thing about powerburst is how it mixes really easily. poor full jug into sprayer and repeat til sprayer is full.
if your using a hydraforce then do the same as above but with 6 scoops instead of 2. you can use a fork to assist in mixing if ya like but i don't personally.
