Attaching playing cards to bicycle spokes is a great way to turn a regular bike into a rockin' MACHINE!

What You'll Need:

• bicycle
• pack of old playing cards
• scissors
• tape

What to Do:

1. Stand your bike upright. The back frame of your bike should form a sideways triangle. (The bar holding up your seat is the base of the triangle.)
2. Tape a playing card to the back frame of your bike, on the bar that angles down toward the wheel. Make sure that enough of the card sticks out to "slap" the spokes as they turn.
3. Ride your bike! The faster you go, the louder the sound will be. NOTE: Over time, you'll need to replace the card as it wears out.
