Getting bored of the usual ollies and kickflips as you skid around with that mediocre skateboard? Why not tweak that deck up with a flamethrower that would surely spark your usual path and leave a blazing trail behind you. This DIY segment would surely turn you into the cool kid with a skateboard flamethrower once you've correctly followed the step by step instructions. If you are underage and cannot legally purchase flammables then we suggest you ask for the supervision of an adult.
Flamethrower skateboard DIY
Get that fire extinguisher kept at bay as you're about to ignite the streets with baby flames. This instructional build is relatively simple to follow and has been demonstrated to give off big results. The below steps are only rough outlines, visit Instructables for the full visual build tutorial.
Step 1: Materials
Before you begin building that flamethrower, you must first haul a few supplies from the hardware store and a simple fuel pump - these should do the job.
-Skateboard (of course)
-12V universal fuel pump
-12V rechargeable power supply
-Arcade style push-button with microcontroller switch
-Universal electronic spark generator
-10 oz fuel canister
-1/4" vinyl tubing
-Hose barb reducer
-Velcro tape
-Hose staples
-Multimeter (for checking circuits)
All in all, this flamethrower project cost just under $100 - not a bad price to pay for such an ecstatic piece of board.
Step 2: Arrange components
Before you permanently attach materials under the board, make sure to do a visual check first - give enough clearance so you can skate smoothly.

Step 3: Attach components
When all the required materials have been perfectly arranged, start attaching velcro tapes on them and stick on corresponding velcros on the underside of the board. Using velcro tapes instead of tough glue, the fuel tank and battery can be easily removed for refueling and recharging purposes.
Step 4: Operating switches
Instead of a hand operated switch, the flamethrower skateboard mastermind opted for a pair of switch integrated on the board for a cleaner look.

Step 5: Electronics
In the words of the build instructor, "The electronics for this project are very easy". Here's the basic electronics layout so you can have a rough idea how to connect things up.

Step 6: Spark installation
This part is the flame igniter and it works by using two electrodes that are close enough to each other for electricity to jump between the tiny gap.

Step 7: Fuel tank
Don't mistake this simple tank to be just a fuel bottle - its cap has two openings, first is for the fuel transfer and the second is there to provide ventilation when the pump is engaged.

Step 8: Barbed adapters
The fuel tank and pump's pipe diameters are different so you'd need an adapter that is barbed for this to hold the pipes in place.

Step 9: Layout
Time to round things up, here's what the underside of the deck should look like. Although this image looks busy, it should still leave enough space between the board and the ground for a comfortable roll.
