Pool Noodle Rainbow

I love to make 3-D decorations! While “playing” with pool noodles making lollipops, hearts, and other shapes, I realized how easy a rainbow would be.

Using the noodles as is after cutting

I found most of the rainbow colors on clearance at Walmart and the rest at Walgreens. Being on end of season clearance I paid around 50 cents each.

I went with the 3” noodles for more flexibility.

Once I had what I needed I started by cutting them in half lengthwise.

Using hot glue and skewers, I attached the noodles to each other forming the rainbow.

When the glue is dry the skewers come out. I decided to attach the entire thing to foam board for more stability using more hot glue. I traced out the rainbow and cut it with an exact knife first.

Since I had the second half of the noodles, I wanted to experiment with making them “tighter”. I filled the center with hot glue and taped them tight to dry.

I repeated the process with all of the colors, then glued them together like the first halves. Honestly, this proved to be mostly a waste of time. There wasn’t much difference in how they turned out although it did give the ability to curve them a little easier. I posted photos of each.

With both secured on foam board, I decided to make clouds to finish the ends. Using more foam board, I shaped out the clouds and attached them on either end using even more hot glue.

On the shaped foam board and end of the noodles, I sprayed foam insulation to build the full puffy cloud effect. After it dried and set thoroughly, I used acrylic paint to get the true white color. Voila! Happy 3-D rainbow🌈
