Just run down to the beach, or to the river, and go into your pockets. Tap the bottle, and then tap "Release." Your bottle will float away.
a water bottle.
because the bottle pop is lighter than the water it floats above the water
it pushes the rocket into the air to make it go higher.
yes it can!because if the rock is heavey then the water bottle can go farthest. OH YEA AM SMART!
If the bottle has a capacity of 100 cm3, you would expect to be able to fill it with 100 cm3 of water.
Because the temperature of water can't normally go beyond 100 degree Celsius , because that is the temperature of boiling water. When we keep any bottle with water on fire, heat transmits from bottle to water and since the temperature of bottle and water should be almost same, the temperature of bottle does not go far beyond 100 degree Celsius. And since the melting point of the bottle(plastic) are in general above 100 degree Celcius they don't melt.
this is a hard question. go figure it out!
Yes, you can bring a plastic water bottle on a plane, but it must be empty when you go through security. You can refill it after passing through security at a water fountain or purchase a sealed bottle of water inside the airport.
By putting water in a clean water bottle cap
It depends on the variables of temperature and humidity. Water evaporates from the wet cloth. Water needs energy (heat) to go from liquid to gas and the water gets that energy from it's immediate surroundings - in this case the cloth and the bottle - so the bottle cools. Only if the air is relatively cold and dry, of course. If it's raining, you won't get much cooling from evaporation. If the bottle is just placed in cold water it is not being cooled due to evaporation and only gets as cold as the water. If the water is flowing and cold, it may readily cool the bottle faster and colder than the wet cloth. If it's just a small bucket of water, it may not cool the bottle much.
to find spring water go to some water and use your empty bottle while facing it it should fill the bottle up with water
