How to make safe cactus needles.
First I started off with some fun foam. These can be picked up at all different kinds of stores. I got these from Hobby Lobby.

I cut out a rectangle piece roughly 2 1/2 to 3 inches long, and cut two triangles out of them.

Then I rolled the base, making the three needles stick out at different angles.

I used a phillips screwdriver to make a hole in the styrofoam.

Filled the hole with some school glue.

Twisted the base of the needles into the hole.

and let it dry.

Ta Da!

Here is a picture of the finished cactus.
