Product description:

Understand the basic principle of buoyancy.

To understand the relationship of action and reaction.

★ understanding characteristics of centrifugal pumps and centrifugal force.

■ understand the basic principle of buoyancy; understand the action and reaction force relations， characteristics andthe centrifugal force; and children brain training skills

■ it and rocket， jet principle machine， is the use of "force" and "force": when the boat water backward jet， with the water "counterforce" and moving forward;

■ impeller rotation can produce a centrifugal force， so that the impeller in the water sprayed from the spraying port，and also generates a suction， impeller below the water suction impeller， pump the general is also using this principlewill lower the water to a height.

■ the toy is a hands-on experiential education model. The ability to strengthen the small friends DIY toys assembled by jet boat.

  The matters needing attention:

  1， before the experiment， please check whether the smooth circuit. Each contact circuit is whether the contact is good? 2， if you have completely according to the instructions for assembling， into the water after the power is notmoving forward， please check the impeller is turned to the right.

  3， can not do the experiment in the river and pond， so as to avoid risk.

  4， experiment， be careful not to be water wet clothes.
