Anyone who has spent any time on a motorcycle has probably experienced some close calls with unobservant drivers. Motorcycles and cyclists are powerless most times to do anything in these situations, other than shake a fist and yell in hopes the offending driver hears your colourful language over their caramel macchiato sips.

Time to fight back! Give 'em a taste of the whack-bonk!

Using a foam pool noodle and a wooden dowel it's time to give a little comeuppance to bad drivers. Add insult to injury by inscribing messages on the noddle, then giving the offending vehicle acouppla whacks to let them know they did you wrong.

Enough talk, let's whack-bonk!

Step 1: Tools + Materials

tools:

hot glue
permanent markers
hobby knife

materials:

wooden dowel (squeegee handle)
pool noodle
empty plastic container
2 x cable-ties

Step 2: Cut Foam Noodle

Most foam noodles come with a cylindrical opening in the centre that runs the entire length of the noodle, perfect for a dowel of the right size. Measure the length of the foam you will need to cover the dowel, leaving room for a handle and a little extra foam at the top to protect the top of the dowel.

If unsure cut a longer portion of foam than required and trim off excess as desired.

Pool noodle is a funny name.But since noodles aren't hollow, these should really be called foam bucatini. But I digress. Where was I? Ahh yes, cutting the foam. Cut foam to length and insert dowel, there should be enough friction between the dowel and the foam to hold it in place. If not, use a liberal amount of hot glue to secure the dowel in place.

Step 3: Holster

You'll also need a place to store your whack-bonk when not in use. I chose a low-tech approach to hold mine, an empty plastic container slightly larger in diameter than the foam noodle.

Remove the top and bottom of the container. Create two small openings on the centre portion for cable-ties which will be used to fix the holster to the bike.

Find an appropriate place on your bike which will accept the whack-bonk. The placement needs to ensure quick deployment while keeping the bike functional. I chose the rear left hand side, just above the passenger pegs. Cable ties were laced through the openings on the plastic container and attached to the turn signal.

Step 4: Share Your Thoughts

Dispensing justice with the whack-bonk is fun, but may not get your message across. You may just look like a lunatic with a large wand striking windshields and yelling muffled expletives inside your helmet. That's why it helps to write out your message to ensure that bad drivers knows exactly why you're so upset.

With permanent marker, embellish your whack-bonk with colourful sayings. Selectively place the sayings around the foam so that you have a choice of message to send.

Step 5: Dole Out Bonks

With your whack-bonk installed, you're ready for the next unobservant driver who is paying more attention to texting their BFF than the road.
Go ahead, give 'em a couple of bonks to pay attention. Let those bad drivers know how you feel with a solid smack and a sassy saying.

Be safe, and have fun! Happy making :)
