To increase the speed at which you mix the Kool-Aid, you can try the following:
Use hot water: Dissolving the Kool-Aid powder in hot water will help it dissolve faster because the rate of a chemical reaction increases with temperature. However, be careful not to use water that is too hot, as this could affect the taste of the Kool-Aid.
Use a blender: Using a blender to mix the Kool-Aid will create a lot of turbulence in the water, which will help the powder dissolve more quickly.
Use a stirring rod: Stirring the Kool-Aid mixture vigorously with a stirring rod will also help the powder dissolve faster by increasing the amount of surface area that is in contact with the water.
Pre-dissolve the powder: You can also try pre-dissolving the Kool-Aid powder in a small amount of water before adding it to the main batch. This will create a concentrated solution that will dissolve more quickly when added to the rest of the water
