This project shows you how to make your own giant toothbrush. They make great accessories for your Halloween costume or award-winning grade-school science fair project. They also make great gifts for the dental professionals in your life.
You can't buy something like this at a reasonable price (call me frugal dad, ok... cheapskate dad) so I started out with some 1x3 wood scraps, scrub brushes, glue and paint to create something big...
This is a great weekend project to do with the kids so they learn some basic woodworking skills, use tools and to watch dad do his magic. Safety first!

Step 1: Layout and cutting wood
Begin by buying scrub brushes that look right for a toothbrush. My first one consisted of two scrub brushes cut and placed end to end to get a large enough toothbrush. The bristle color should probably be white for the right effect. The blue bristles make a cool color border that looks like an expensive toothbrush. I found my scrub brushes at a dollar discount store. We are looking for proper proportions so you can easily make a really giant toothbrush with one of those big sweeper broom heads.
Next, get some 1x3 wood stock about 4 feet long. Furring strips will also work if you want to take the extra effort to patch, sand, and round over the edges to make the finish look nice. This time, I found stock that is used for bed slats. It is a bit thicker than the standard 1x3 stock, already has rounded edges and has a little more heft to it due to the species of wood used.
Starting from one end, measure about 2 brushlengths long. This is a creative project so exact measurements are not needed. On the edge, draw about a 30 degree diagonal line from that point. You will then saw the wood through making two pieces. Extend the lines down the wide fronts as saw guidelines. You can use a hand saw or various power saws to cut. A bandsaw would probably be nice for this project but it is not necessary.
