This is the final product.
These are the materials we used:
-foam to construct the straw out of
-glue to glue the pieces of foam together
-a drywall keyhole saw to cut the foam
-paint to paint the straw after it was cut
-measuring tape to measure the length and width of the straw
We measured the foam and cut the length at 71.25 inches and the width at 4.5 inches.
We cut the foam with a drywall keyhole saw.
We had some difficulty with this saw, you might find it easier to use a laser cutter.
We cut the foam and cut it at a curve to outline the straw.
We had to spray the foam with plastidip before we painted it. Here is a picture of the plastidip we used.
You have to spray multiple layers of plastidip on the foam in order for it to stick but be careful because too much can eat up the foam.
We painted the straw orange. Here is the orange paint with paintbrushes.
After completing all of those steps, you get a giant orange straw!
