Science Teacher Builds Drill-Driven Conveyor Belt for Halloween Treats
Donald Clark is a seasoned science teacher currently at the Long Branch High School. He has an inquisitive mind who can't help tinkering with stuff and coming up with new inventions.
In his latest feat, Donald had the idea of building a conveyor belt that fed snacks to a chute, which then delivered treats to a bowl on the curb 8 ft away (~¨2.5 mt).
Donald told APP that he was inspired by ziplines created with others. He told Daniel Radel from APP, "I saw those, and I thought, 'I've got to come up with something better." If you're curious about what inspired him, be sure to check out a spooky example we've covered recently.
How it was built
Donald utilized a canvas drop sheet for the belt part and put paint rollers as shafts. There are also green separating blocks (seemingly styrofoam) embedded on the sheet to help keep the snacks nested in their place on their journey up.
He told us in a mail "I tried to just tap a thread on the metal roller after cutting off the plastic handle but did not work. I removed the whole handle and just used a roller cage with a 12 inch threaded rod,"
He continued "The belt is a small canvas tarp cut in strips and sewn up. I made a tensioner with an extra piece of wood and two wing nuts." But that didn't wasn't enough, it didn't track well. So he made a sideways slot in the lower nut to adjust it side-to-side.
To power this belt, he uses a hand-held electric drill. Once snacks reach the top, they are fed to the chute which bids them farewell to the curb approximately 8 feet away (`~2.5 mt). The whole thing took him two weeks to build.
Donald notes "This is all performance art. I get to invent something and I get to do something the kids will really enjoy." He has three adult kids and told APP that he has even performed as a clown years ago. He also noted that he's stocked up three large bags of treats as he's gotten the word out about his contraption.
Have a safe Halloween folks.
