Salt Water Fuel Car




Our newly introduction of the next generation of Clean Energy with this Salt Water Fuel Car Kit. Using simple chemical reaction, energy is produced to run the motor to power the car. All you need is Salt Water. One drop of salt water can power the car up to 15 miniutes. Yes Salt Water. Just add salt into a glass of water n stir it properly and you'll get the solution. Too much salt is better than too less salt.

Salt Water Fuel Car: SGD 23.90
Replacement pack: SGD 4.00 (part include: nonwoven fabric (white) & magnesium plate (shinning silver)


Troubleshoot:
Q: I've fixed the salt water fuel car and dripped the salt water but its not moving.
A: Make sure enough salt is used in the water solution (too much is fine)


Make sure the layers are correct. First, air cathode (black), then nonwoven fabric (white) and finally the magnesium plate on top (shinning silver)


The cartridge may be pushed in too far or not far enough. Slowly push in or pull out until the wheels start spinning.

When trying to get car to work, make sure your hand is not on back wheels keeping them from spinning.

Q: I've fixed the salt water fuel car it starts moving but when I place it on the ground it didnt move.
A: Please make sure there is no sharp edges on the wheels and the cartridge. As it will stop the car from moving.

Q: The second time we play with it, it wont move.
A: When finish playing make sure you rinse the air cathode (black) plate *BUT DO NOT SCRUB IT*, wipe gently on the nonwoven fabric (white), and most importantly rinse n wipe all salt on the magnesium plate (shinning silver) as the chemical reaction will oxides the magnesium plate then it cant be used again.


Q: I've clean the parts but it still can't move the second time I play with it.
A: If the magnesium plate (shinning silver) is badly oxides it can't used. You can try scratching off the oxides area wit a coin.
  
The 2 silver part which connected to the motor with the wire might be oxides as well. so please check that specific part. If it is oxides scratch it off. this part must be placed nicely as: if bend it inward it will stop the car from moving. if bend it outward it can't connect to the cartridge.

  1. I've lost the Non-woven fabric to the salt water car, any idea on where I could get more of it?

  2. The non-woven fabric is available in the refill pack. The refill pack include 2 X non-woven and 2 X magnesium plate. It cost $4 for the pack. You can purchase it from us. The problem is that we cant sent it by mail to your resident due to the magnesium plate. If you want to purchase it you have to either come down to our science fair in the school or our office which located at Tagore Drive.
