BOATS
Fun and educational
| Following are three different types
of boats used by students for science projects or other educational
experiments. All three boats are also available as a set with a
discounted price. These boats demonstrate three different propulsion
mechanisms of air power (wind), steam power and mechanical
propeller. These boats show how energy can be converted from one
form to the other.

We will soon add more samples of science
projects that use boats.
| Candle Powered
boat
This tin boat has a small steam
boiler tank mounted inside the boat. The tank is connected to two
brass exhaust pipes used to enter water and push out steam. This
boat is famous for the pot-pot sound that it makes while the steam
starts rolling. This boat is a simple steam propulsion boat. Use the
eye dropper (provided with the boat) to fill up the tank with clean
water.

Start entering water from one brass pipe
and continue until some water exits the other pipe. Place a candle in the
candle holder, light up the candle and push it forward so the flame will be
directly below the tank. Soon the pot pot starts and boat moves. Paddle in
the back of the boat can be adjusted so the boat move in a circular path.
Candle powered boat is not recommended for
very young children. It uses open flame of a candle that can cause burns and
fire if neglected. Adult supervision is required where students use this
boat as an educational tool.
| Balloon Powered
boat
Balloon powered boat is made of
wood and comes with three balloons. The air from the inflated
balloon exits the pipe in the back of the boat, pushing the boat
forward.
Some students make wheels for the
boat so they can perform experiments without having access to water.

| Balloon powered boat is a classic
wooden toy that will bring hours of enjoyment to children of all
ages!
Simply place the un-inflated
balloon over the lip of the rounded cylinder as shown in the
pictures and inflate the balloon by blowing air into the wooden pipe
at the back of the boat.
Once the balloon is fully inflated,
cover the tail pipe with your finger to keep the air from escaping
the balloon. Remove finger from the tail pipe and watch in amazement
as your boat cruises through the open sea or bath tub!
