Looking for a cool science fair project? Forget the exploding volcano, check out this Articulated Hand project!
“My niece Sydney needed help for a 7th grade Science Fair project. I helped another friend’s daughter (Kaitlin) build an articulated hand for a project in the past and suggested we resurrect the project. The build is fun for the kids and I wanted to try some enhancements on the original idea.
You can get everything you need at Lowe’s or Home Depot.
1 – 3/4″ hardwood dowel
1- 4″ x 1″ Pine plank (I’m calling it ’1×4′ here)
5 – bags of #216-1/2 small screw eyes (eyelets)
1 – roll of braided nylon string (one color for ligaments. We used yellow)
1 – roll of braided nylon string (another color for tendons. We used pink)
1 – bag of 1/4″ wide rubber bands (like the Post Office uses)
1 – cup hook (open eyelet)
1 – can of white spray paint
2 – 3/4″ sheet rock screws
Various hand tools (you already have them if you are a maker!
We used a small drill press, 4″ side grinder, jig saw (my Dad taught me this was called a “Saber saw”) and a chop saw with a trim blade. These are time savers, but you could do it all with hand tools if you can spend the time.”
