2. Aim
We wanted to find out if a small boat could
be powered by gas made by baking soda
and vinegar together . We did two different
experiments to see if we could get ours
going.

3. METHOD: 1
We got a bottle and put a x in
it and a straw in the x then we
put hot glue around the x to
seal it. We put vinegar and
baking soda in it, shook it up
with our finger over the straw
and put it in the pool.

We used popsicle sticks to make skis
and glued them to the bottom of the
boat to make it stable.

5. WHICH BOAT DO YOU THINK WORKED THE BEST?
BOAT 1
BOAT 2

6. YES
The second boat worked better than
the first boat. This was because we put
skis on it which kept it stabilised. More
vinegar and more baking soda might
make it more powerful but it was
already quite difficult to get the lid on
in time to trap the gas inside.
