Pencil Power

See what you can make with just pencils and rubber bands!
Supplies 2 packs of pencils 20 rubber bands Instructions Make a square with 4 pencils lying flat. Connect each eraser with rubber bands. Attach one pencil standing upright to each corner. Attach 4 more pencils to create a square on top of that. Take 4 more pencils and attach at one end. Bring the ends of those together to create a point or triangular shape. Attach 3 more pencils above that to make the point or antenna of the building. Ideas How long can you make a pencil antenna before it topples over? Can you make a long pencil pointer and write with it? (How long can you make it before you lose control?) Can you make other buildings or geometric shapes out of pencils and rubber bands? See Triangle Stand for another idea.)
