TEK Tuesdays: Spoon Racer

How to build a Spoon Racer that slides and sways!

Parts you’ll need:

• 1 Motor (available at The TEK Center)
• 1 Double AAA Battery Pack (available at The TEK Center) 
• 2 AAA Batteries
• 3 Corks
• 1 Disposable Spoon
• Hot glue gun & glue
• Wire Strippers
• Scissors
• Screw Driver

STEP 1: Cut off the tips of the battery pack wires using scissors or wire cutters.

STEP 2: Strip the plastic casing off the ends of both wires to 15mm.

STEP 3: Twist the exposed wires to create solid ends. (Do not twist red & black wires together.)

STEP 4: Insert the exposed wire end through the motor pin and fold toward the encased wire.

STEP 5: Twist the motor 2-3 times until the wire is secured onto the pin. (Then repeat the process for the other wire.)

STEP 6: Insert batteries.

STEP 7: Test to see if the motor works.

STEP 8: Cut the cork exactly in half. (Be careful to keep your hands and fingers clear from the blades, the scissors can easily slip!)

STEP 9: Now cut the same cork into quarters.

STEP 10: Hot glue the quarter pieces onto the 2 remaining corks as shown below. (Allow to dry and then add a little more for stability.)

STEP 11: Using a screw driver, puncture a hole into both “cork wheels” off-centered and only half way through the cork. (Twist the screw driver a few times to widen the hole.)

STEP 12: Hot glue the spoon onto the top of the motor. (Make sure the spoon faces the correct direction.)

STEP 13: Place the “cork wheels” onto the motor axle with the off-centered holes facing opposite directions. (This creates a cool “sway” effect.)

STEP 14: Hot Glue the battery pack lid onto the spoon handle. (Make sure to leave enough room for the wheels to spin freely.)

STEP 15: Allow the glue to dry and then test out your awesome Spoon Racer!
