How do you keep an ice cube from melting with out the use of a Styrofoam cup and a Styrofoam cooler?

Question

Science Project

Answer 1

Ice water.

Answer 2

Going by your question, it seems like you are doing a science project on insulators. You need to prevent heat from reaching the ice cube, which would cause it to melt. There are many other materials to use besides styrofoam, but first we must look at the three different ways in which heat is transfered, so we can find ways to prevent that heat from getting from the outside to the inside where your ice cube is. You must prevent radiation, which is done easily enough by any kind of reflective material (the shiny side of aluminum foil, for instance). You must prevent against convection, which is also pretty simple- you just need to provide a physical barrier in between the ice and the outside (cotton, any kind of foam, down, anything light and fluffy works fine, but you must have a more substantial barrier on the outside- say cardboard, which would prevent air currents from getting the the ice). Conduction is the third type of heat transfer and it is your biggest adversary. Just putting material around the the ice will help with this- like cotton, any kind of foam, down, anything light and fluffy. Goodluck with your project!

Answer 3

In the old days they did not have Styrofoam, they would build a wooded box, and put it in a larger wooden box surrounded by saw dust. That was how it was done, you could do something like that, or make a home made ice chest, using a plastic bag stored in a box with some insulation or paper around it for insulation, shred the paper

Answer 5

store it below 25 degrees. use gel packs and non-Styrofoam coolers. use newspaper. use dry ice. place it outside in the snow.

A freezer filled with stuff is colder than one that is nearly empty so you could put a lot of frozen foods in there with your ice cube.

You didnt say anything about where--so following the rules, with no Styrofoam I have to say "leave it in the freezer"

Answer 6

Without a time frame and ambient temp this is not a valid question. You can make, essentially, a cooler with this stuff but if the temp is above 32f you cannot keep ice from melting but you can slow it down.

Answer 7

put about 1/3 pounds of dry ice in the cooler, put the ice cube in the cup, viola! not only will it make a cool mist if you pour water on it but it will keep that thing frozen for a really long time

Answer 8

I know the perfect solution if you are just starting with woodworking and also if you have already experience with it. I reccomend to give a look to this website ( woodworkingplans.kyma.info ) You can find a lot of woodworking plans and you will be able to manage the projects with a CAD/DWG software. It allows you to modify the projects and to alter the arragements. If you are a beginner this is the easiest way to start, it's the best approach to woodworking; and if you already have experience you will find a lot of ideas and inspirations to improve your abilities with woodwork. I'm sure that you will love it!

If you are planning to start on your woodworking project, this isn't something you should use, it's something that you would be insane not to. Go here https://tr.im/iikOV
Truth is, I've been a carpenter for almost 36 years, and I haven't found anything like this for less than 10's of thousands of dollars.
