Glass or Plastic Cup
1/4 cup of vegetable oil
1 teaspoon of salt
1 cup of water
5 drops of food coloring
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.
The hypothesis for the "lava in a cup" experiment may be that when vinegar (acid) is added to baking soda (base), a chemical reaction will occur and produce carbon dioxide gas, which will create bubbly "lava" in the cup.

The dependent variable in a lava in a cup experiment is typically the height of the "lava" (baking soda and vinegar mixture) that erupts from the cup. This variable is measured and affected by the independent variable, such as the amount of baking soda or vinegar used.
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.

To make a 6 oz cup of coffee, you typically need about 1 to 1.5 tablespoons of coffee grounds.

Lava in a cup is a simple experiment that demonstrates the concept of density. The dish soap, water, and oil have different densities, causing them to layer on top of each other. When food coloring is added, it creates the lava lamp effect as the colored water blobs rise and fall through the oil.
no
no it will smash and make u messed
