cup
this is the model of a volcano's lava.
The problem of lava in a cup is that it is extremely hot and can cause burns if touched. Additionally the rapidly expanding heat from the lava can cause the cup to break creating a potentially dangerous situation. The following are some of the issues associated with having lava in a cup: The lava is too hot to touch without causing burns. The heat from the lava can cause the cup to crack or break. The lava can cause the cup to become very hot to the touch making it difficult to handle. The lava can cause the cup to become brittle and break easily. The lava can also cause smoke or steam to be released which can cause irritation to the eyes nose and throat.When dealing with lava in a cup it is important to take the necessary precautions to ensure safety. This includes wearing protective gloves and eye protection keeping the cup away from flammable materials and keeping the cup in a safe place away from children and pets.
the salt hits the bottom and dissolves
foam cup is a poor conductor of heat! haha;] msg me!!
cup
It's only an experiment if 2 or more conditions are compared. Lava in a cup is a science observation or demonstration. To make it an experiment, you would have to compare 2 conditions, for example lava cups with salt vs. lava cups with baking soda while keeping all other variables constant.

by salt
The rate of heat loss from the hot cup decreased during the experiment.

you can make a lava lamp that can last for about five minutes. all you need is a transparent cup,olive oil,water and salt. what you'll need to do is put about 1 third of the cup some olive oil and then fill the rest with water (you will notice that the oil and water seperates the oil goes to the top and the water goes to the bottom.)now carefully pour some salt and this will act as a lava lamp. Another fun experiment is using science to crush a can, http://www.youtube.com/watch?v=-gP0w6UPSlY the link is to a youtube video that takes you through the method check it out!!!
