Introduction: Erasinator

The first grade class at Frick Environmental Charter School investigated problems in their classroom. They found that they could make the process of erasing their whiteboards faster and better, and came up with an invention called the Erasinator.

Step 1: Get Your Supplies

Picture of Get Your Supplies

Mini whiteboard
Power drill
Saw
Sand paper
Wire
Mini dowels
Straws
Erasers (2)
Thin wood
Ruler
Sand paper
Gorilla glue
Hot glue gun

Optional:
Spray paint
Logo stencil
Paint

Step 2: Attach the White Board to the Wood

Measure and saw your piece of wood so that the whiteboard will fit on top of it, leaving several inches of space on the wood at the top and bottom.

Spray paint your wood. (Optional.)

Use hot glue to set the whiteboard centered in place on the wood.

Step 3: Glue Erasers

Glue two erasers (or whatever width fits the width of your whiteboard) with Gorilla glue and set it aside to dry. Be careful to follow the directions on the Gorilla glue.

Step 4: Measure and Drill Holes

Plot the holes that will hold the wire. You will need six holes: two at the top of the wood, two at the bottom of the wood, and two through the erasers on the ends. Make sure the holes are lined up so the wire can stretch across in a straight line.

Cut the straws and put them through the eraser holes to make them stronger, so the holes don't rip when the wire presses against them.

Step 5: Put the Mini Dowels in the Holes

Make a wire-sized hole in each of the dowels. Slide the mini dowels in the holes, making sure they fit in snugly.

Step 6: Add the Wire

String the wire through and around the dowels, continuing through the eraser holes and to the dowels on the other side. You should be able to adjust the wire by twisting the dowels around until the wire is tight, but the wire should still be loose enough to let the eraser slide over the board. Add Gorilla glue to the dowels to keep them in their position.

Step 7: Optional: Add Your Logo

Draw or paint your Erasinator logo on your Erasinator. We used a stencil we made with a laser cutter and painted our logo on.
