Cardboard Marble Racer

I made one marble racer with the pool noodles, but I wanted one like the large wood ones, that had the marble race down one inclined plane after another.  No wood and the tools are not set up in the new wood shop yet.  I scavenged a nice sized cardboard box, which sat in the back seat of my car for about 2 weeks while I thought about it.  Finally, I had the time to create what I had spent quite a bit of time thinking about.  So this is how I made a cardboard marble racer.

Step 1:

Supplies:
1 large cardboard box (mine was 19”x15”x14” (48cm x 38 cm x 35cm))
Spray paint (you choice of colors- I used leftovers from other projects)
20 1½ inch (4cm) brad fasteners (office supply store +/-$3)
Yard stick
Pencil
Craft knife (+/- $3 depending upon what you buy and where)
Marker 
1½ inch (4cm) masking tape (stuff I had)
Awl (one I have had for years)
Masking tape (not shown)
(I showed glue but I didn't use it)
