No chemicals can be used at all.

Also, the lense was one of our ideas but the problem is the experiment is conducted indoors under fluorescent light. So do you think the light would give enough energy. Another very simple idea was to place the ice in a zip lock bag and drop the bag into a beaker with water at room...

Wysard, boiling water can't be used. Any additional water used must be at room temp.

Gravity is passive. But how high would you have to place the ice cube to actually have some sort of effect. The experiment would be carried out on a table. Here is some more information. Project Statement: The project team is to design, analyze, build and test a "passive" heat transfer...

Above is a few of the frequently asked questions. If we used the plates, would it be best to place it in some sort of container? We were thinking of designing a box made from acrylic with holes in the bottom and top to all air to flow. Should be do that are just let it sit in the air with no...

Q: Can solvents be added to the ice? A: No, nothing can be added to change the chemical composition of the ice or that creates an endothermic or exothermic reaction. Clarification: in any part of the device, no substance that creates an endothermic or exothermic reaction is considered to be...

Thanks a lot of the comments once again. Heating is not allowed. You can only heat it up using the light in the room which is useless. Also the ice cannot be crushed before the experiment, it must be crushed by some means during the experiment. The vertical tube is a great idea. But in terms of...

Thank you very much for the comments. Changing the pressure would be best, but unfortunately, we can't use any external source. The only external sources we can use are the room temperature and gravity for instance.

I am working on this project where we have to melt some ice in about 2 mins. The experiment will be taken place indoors, at room temperature. We have to melt as much ice as possible in that time. No salt or any chemicals can be used. Conduction or convection is all we can do. Any suggestions for...

Question: What is the best way to melt ice?
