I do remember doing this in grade school and have many pinterest pictures of this from various sources, but I saw this more recently on Artful Parent!
Using a Salad Spinner for art fun!
Found this gem at the thrift store for $1 (half price day).
You can cut paper, use paper plates to fit inside, or use coffee filters- which fit perfectly.
We tried both.
Add paint or liquid watercolors or food coloring/water...and...SPIN!
This was the fun part, my girl loved it! Remove the lid and see what you made...
We then played with it some more...added some glitter and white paint!
Gave it another spin...and...
We also did the classic record player spin art. I remember doing this as a kid too! So fun.
