Slip the balloon inside the neck of
the bottle and stretch the mouth of
the balloon over the bottle top.
Take a deep breath and try to
blow up the balloon inside the
bottle. Remove the balloon, fill the
soda bottle to the brim with water,
and then seal it with a cap. Punch
a small hole with a nail and
hammer in the side of the bottle,
close to the base. Remove the nail,
uncap the bottle, and empty the
water out the top. Place the
balloon in the bottle again (Step 1)
and try to blow up the balloon.
Quite a difference! Blow hard until
the balloon fills most of the bottle
(a little water left in the bottle
helps). Place a finger (or thumb)
over the nail hole when you stop
blowing. Now, move your finger.
Place thermometer in 2 liter and
observe temp; pump fizz keeper
10 times and observe temp; repeat
