I did this craft with my children. Its a pretty simple premise. I’d suggest the kid doing this activity be about elementary age. It sounds easy to you and me, but it can become frustrating for a younger kid still developing their hand eye coordination and dexterity.
Materials needed are construction paper cut in a U shape, tissue paper cut into small squares, glue, pen or pencil, white paper crumpled.
Take your U shaped construction paper and dob a line of glue along the edge. Take a square of tissue paper and wrap it over the eraser end of your pencil. Turn over and place on the line of glue. Repeat process until the entire row is full. After you finished one color, go back to the glue and start the next row of color.
Once you’ve filled your entire rainbow, take your white paper and add some glue to it. Place and hold onto the ends of your rainbow for a few seconds until the glue takes hold.
My younger child gave up the pencil and took to crumpling the tissue paper into balls and putting those on the glue. It actually turned out just fine. If your child is having trouble with the pencil and paper, you can show them how to crumple the paper instead.
Allow time to dry of course, and the hang on the fridge, or in the window, or on the wall. Or your kid can run around showing everyone they see their pretty rainbow.
This craft was a little bit of a challenge for us. I’d say it took a good 30 minutes to and hour and then time to dry. My child got frustrated and walked away a couple times. But this activity pushed the limits of their ability, and helped improve it.
