Dry Ice Bottle Rockets
Dry Ice Bottle Rockets:
Materials:
-Water
-Scissors
-Pop Bottle
-Drill
-Ice pick or hammer
-Tape
-Box
-Gloves
Procedure:
To build the dry ice rocket you need to cut a hole in the bottom of the box large enough to fit your bottle into it in a standing position, and place the box in the launch area.
Than drill a small hole in your bottle cap and then cover the hole with clear tape. After fill the bottle 1/3 with water. Break up dry ice with ice pick or hammer while wearing gloves. Place enough dry ice into the bottle to finish filling the bottle to the halfway mark. Screw the lid tightly, place the bottle upside down in the box and move away at a comfortable distance.
Inventor:
Adrien-Jean-Pierre Thilorier (1790–1844), discovered dry ice while no the inventor of the use of dry ice in a bottle rocket is unknown.
They work by using dry ice (Solid CO2). One of dry ices properties is that it converts directly from solid to gas at room temperature, a process called sublimation. The CO2 quickly sublimates in water and shoots bottle up. The pressure will build in the bottle until it pushes through the tape to vent, causing the rocket to shoot up. Dry ice rockets can be unpredictable, so the rocket may move horizontally. The temperature of water affects the sublimation, more molecules in the dry ice will have the minimum required energy to overcome the intermolecular attractive forces of the molecules if the water is warmer. So, a higher temperature will provide more energy so more molecules will sublime at a faster rate. Cold water will not provide as much energy as warmer water would. The volume of the dry ice and water will also affect the results because not enough CO2 wouldn’t create a sufficient amount of pressure to shoot the rocket up.
