Week 8: Materials and precautions

(Please note that the experiement may be changed as further testing is performed)

Materials/equipment

-5 Various bottled soft drinks, 1.25L each.

(Must include a home brand such as No Frills)

-Pack of balloons (at least 2 for each bottle of soft drink)

-Safety goggles

-Flexible measuring tape

-Duct tape

-Heavy black marker

-Ruler

Safety precautions

-Keep a safe distance away from the balloon as it is inflating; it may explode.

-Furthermore, wear safety goggles as soft drinks will cause severe irritation to eyes.

-Please take care to keep movement of the soft drink bottles to a minimum (especially during transport), to prevent gas building up inside.

The general idea of this experiment is to wrap a balloon over the lid of a soft drink bottle, open it while the balloon is deflated, and then measure the balloon after it has inflated.

Possible flaws:

-There is not enough gas inside the bottles to inflate the balloon enough to measure.

-There is too much gas inside the bottles, leading to leakage or explosion.

-The balloons will be too small to properly wrap over the lids and/or to open the lids through it.
