Instructions
Pour equal amounts of water and rubbing alcohol into the bottle. Fill the bottle a fourth.
Deposit several drops of food coloring into the mixture. Put the lid back on the bottle and shake the bottle to mix the food coloring.
Remove the lid and use the drill to drill a hole in the center of the lid that is slightly larger than the straw.
Screw the lid back on the bottle. Insert the straw through the hole in the lid and into the liquid until the end is half an inch from the bottom of the bottle.
Glue the straw in place. Position the straw so it is straight up and down then squirt a small amount of glue around the straw where it touches the lid. Hold the straw in place until the glue dries.
Mark the bottle. Place the store bought thermometer against the bottle and mark the level of the liquid in the straw with a line then write the current temperature next to it.
Heat the thermal meter. Place the bottle next to a heat source. The liquid will rise up the straw as the temperature rises. Use the store bought thermometer to gauge the temperature and mark the level of the liquid in the straw every ten degrees. Slowly increase the temperature of the heat source and record the changes to the liquid in the straw.
Cool the thermal meter by moving it away from the heat source. Allow the bottle to cool to room temperature then place it in a bowl of ice. Mark the level of the liquid every ten degrees as the temperature cools.
