Dry ice is solid carbon dioxide. Have you ever wondered what would happen if you microwaved dry ice? Here's your chance to find out, without risking your microwave!
First I've compared dry ice in water, in the microwave compared with left out on the countertop. The microwaved dry ice in water is nearly gone after a minute in the microwave because the microwave heated the water, causing the dry ice to sublimate more quickly.
Next I compared dry ice on a plate in the microwave to dry ice left on the counter. Although the microwaved plate became very hot, the dry ice was unaffected. The microwaved piece of dry ice and the control piece of dry ice were comparable in terms of shape and size.
The reason why dry ice is unaffected by microwaves is because carbon dioxide is a linear molecule with no electrical polarity. The electromagnetic waves given off by the microwave don't really interact with the nonpolar molecule, so nothing happens.

In this video we turn copper pennies into silver and finally to gold.
Obviously it's a chemistry trick but still impressive.
First we get 30g of zinc sulfate and dissolve it into 100mL of water.
Zinc sulfate was made back in our video on making a copper sulfate and
zinc battery: http://www.youtub...
If you don't have zinc sulfate or can't make it, you can also use zinc chloride. This can be made by simply mixing hydrochloric acid with zinc metal and waiting until the fizzing stops.
Then we drop in several cut strips of zinc metal.
Zinc metal was obtained from our video on getting useful materials from batteries: http://www.youtub...
The solution is heated to a boil and copper pennies, that have been thoroughly washed/cleaned, are dropped in. They must touch the zinc in order for this reaction to work. Leave it in for five to ten minutes.
The zinc metal dissolves and releases electrons that go into the copper and give it a negative charge. The zinc ions in solution now redeposit form a thin layer of zinc metal. Giving the coin a silvery color.
Now the smart physical chemist might wonder how this can possibly work. Overall we're going from zinc metal to zinc metal and at first it seems like we're missing something about thermodynamics. What is the driving force? I've searched the literature and there doesn't seem to be a consensus among scientists, some claim it's a surface free energy issue with zinc having a lower potential on copper than in free solution (at high concentration). Others state that its an alloy of zinc metal and copper on the surface. The silvery color you're seeing on the penny is actually a type of white brass, not pure zinc. This is thermodynamically more favorable than pure separate metals and thus serves as the driving force.
Anyway, whatever the specific chemical reason, we've now deposited zinc onto copper.
The most amazing trick is to turn it into gold. Simply wash the coin and place it on a hotplate heated to about 300 Celsius. As it heats the zinc will diffuse into the copper, forming brass on the surface that looks like gold.
Eventually it will wear off but the results are rather impressive.

Ƹ̵̡Ӝ̵̨̄Ʒ Nail FAQ Ƹ̵̡Ӝ̵̨̄Ʒ
♥ I use acrylic paints because its waaaaay easier to draw with than nail polish. Not to mention if you do nails as much as I do it's a lot cheaper.
♥ I always use nail polish as the base color and then do the art with paints.
♥ My favorite brand of paint is Americana and you can see them at the end of my videos.
♥ Why haven't you done my request? I have loads of requests and I bought a book just to keep them all in. If I went in order the requests are behind by a few months lol. I don't go in order anymore but I always look at the book when making new designs.
♥ I record with my JVC Everio camcorder and use Sony Vegas Pro to edit.
♥ How do you place your camera to record? I use a tripod and place it in front of me of a table. There is a picture of it on my facebook.
♥Between coats I normally wait between 5-10 minutes to let the layer dry.
