Watch this racer speed along
using the power of air. Blow up the balloon using the car’s exhaust pipe, let go
and watch your balloon racer fly across the floor! It is Newton’s third law in
action and an awful lot of fun too. Set up a race track and have the two
included cars race each other.

What
you get
Two
balloon racers in a blister pack. The racers can be used again and
again.
How
does it work?
Place the car’s plastic exhaust
pipe in your mouth and blow up the balloon. Hold the car with one finger firmly
over the exhaust pipe to prevent air escaping and the balloon deflating. Let it
go and watch the air whoosh out backwards, propelling the racer forwards at
surprising speeds. The balloon racer will whistle and zoom until all the air is
expelled. Never under-estimate the power of air.
