We have done color games for three years now and each time we figure out better ways to do things. In the past we have used funnels to put the color powder into tube socks. This is difficult and messy as the powder does not want to go easily through the small end of the funnel. Through trial and error today someone came up with this method that works well.
1. Take a plastic cup
2. Put the tube sock inside the cup then fold it down around the outside of the cup
3. Fill with desired amount of color powder. In our case an amount that filed the cup was perfect
4. Pull the sock back up and tie off.
It’s still a pretty messy project no matter how you do it, but this made the process a lot easier.
