A Bunkie board (or piece of plywood cut - to - size
at a
home improvement store) helps add stability to the top bunk, and is more attractive when
seen by the bottom bunk, especially if you paint it.
The materials for the Science Buddies wind tunnel (
see Figure A) were almost exclusively bought from Lowe's
Home Improvement, The
Home Depot, and a locally based hardware
store, but they are readily available and can be found
at a variety of locations.
