zoom across the floor with a whistling sound.<br />
Great for teaching Motion & Newton’s Third law.<br />
Size: 167 x 85 x 32 mm<br />
Included: One racer, two balloons, 1 whistle, 1 sticker set<br />
Age: 7+<br />

Air & Water Pressure Kit<br />
Such a fun way to get to know about Boyle’s law! Use the<br />
large cylinder and piston with the other tubes to investigate the<br />
compression of air and water. A number of experiments are<br />
possible from the included worksheet but the best is the making<br />
of an air gun to shoot the safe foam stoppers (included).<br />
Or use the tube to shoot potato pellets!<br />
The safety guard protects your hand from any injuries.<br />
Age: 9+ with adult supervision<br />
F38 A$ 9.00<br />
Fire Syringe <br />
Watch a small wad of cotton burst into flames when it is exposed<br />
only to the heat of rapidly compressed air. Vividly demonstrates<br />
the adiabatic ignition principle of the diesel engine (with no spark<br />
plugs). The auto-ignition temperature of cotton is around 229 0 C<br />
and that is what the air gets up to in the tube! <br />
Included: Base, cylinder, fiber pack & replacement o-rings.<br />
Teacher demonstration only.<br />

Mighty Missile Launcher <br />
This is such a clever design and set-up. The air in<br />
the balloon is squished from it with a blow of the<br />
hand and the missile zooms off to 3 meters. You<br />
can adjust the amount of air, direction and angle<br />
of flight. Students can try to reach a target by<br />
changing the variables. A cool & neat design! <br />
Safety: Missiles have soft foam points but eye<br />
protection is recommended. <br />
Included: Launcher, balloon, 4 missiles <br />
Age: 7+ with supervision <br />
F33 A$ 10.00<br />
Four Wheel Project Kit<br />
This kit is ideal for projects needing free<br />
running wheels, axles and a base to<br />
mount components such as an electric<br />
motor, fan, solar cell, balloon, etc.<br />
Included: 4 wheels, 2 axles, tape,<br />
210 x 60 x 3 mm plastic board chassis<br />
and rubber tube.<br />
