Measure out the Kool Aid powder packets and pour them into a blender.
Add the ice cubes or crushed ice to the blender, filling it about three-quarters full.
Poure the cold water into the blender to help facilitate blending and achieve the right slushy texture.
Secure the lid tightly on the blender and start blending on high speed. Blend for about 30 seconds, or until the mixture is smooth and icy, with a slushy consistency that’s scoopable and vibrant in color.
Stop the blender and check the consistency. If it’s too watery, add more ice and blend again until it reaches the desired thick, icy texture.
Use a spoon to scoop the Kool Aid slushie into glasses or bowls, revealing its bright, colorful appearance and icy texture.
