Tip

Don't push the WHEEL W/O COATINGS too firmly against the frame. It has to leave about 1 mm of space between the WHEEL W/O COATINGS and 9 HOLE RODS, and they are able to spin freely.

Done!

You will need

Your water car, some water and a route that can get wet.

Here's how 1. Remove the PLASTIC BOTTLE from the model, fill it with half of water and put it back.

When installing, make sure that the 80mm

TUBE B is bent so that it could touches the lower wall of the bottle.

2. Apply pressure 50 to 60 times to build pressure in the bottle.

3. Place the model on a firm surface route that can get wet, and then remove the RE-

LEASE CLIP from the model. The mixture of air and water will be poured out of the back and the car will shoot forward.

4. Now repeat the experiment without filling the bottle with water.

What is the effect?

WHAt'S haPpEnInG?

After removing the RELEASE CLIP, the air/water mixture will escape from the nozzle in high speed and the model will shoot forward. On the next page, you will find the reason for this situation and why the car can barely move forward when there is only air in the PLASTIC BOTTLE.

Tip

Make sure the 80mm TUBE B touches the lower inner wall of the PLASTIC BOTTLE. Otherwise, only air may escape from the nozzle. If air or water effluences from the bottle, check that the OD15.8 FLAT O-RING is properly seated and the PLASTIC BOTTLE is tightened.
