Cut and glue a piece of green card stock around a potato chip can.
Ask an adult to cut a slit in the side of the can large enough for bills
to easily slide through. Decorate the can with coin stickers.
Use a quality tape, testing it first to make sure it will peel off
without damaging the bills. Tape the bills together along one end so you
have a long line of bills. Roll them up and place the roll inside the
can. Poke the end of the first bill through the slot to the outside of
the can.
When you pull on the bill, dollars will dispense and will seem as if
you have a money machine with an endless supply of money.
