Science Experiments How-Tos

How To: Perform ballistics comparisons

In this scientific video tutorial, undergraduate students in a forensic chemistry lab demonstrate how to use a comparison microscope for bullet and bullet casing comparisons, and color developments tests for impression marking enhancement (such as for filed-off serial numbers). Learn how to perform ballistics comparisons! Just like in CSI.

How To: Build a vertical axis wind turbine

The economy is down, so what's one way you can save money? Build a vertical axis wind turbine! This eco-friendly four-part video tutorial will show you just how to make one so you can save money. These are detailed steps for making the vertical axis wind turbine. The blades can be easily interchanged offering different shapes and materials to experiment with. This design can create turbines up to 90 inches in diameter and up to 15 feet tall.

How To: Make burning soap bubbles

Learn how to make bubbles burn in this science video tutorial. You will see exactly how to make burning bubbles, with aerosol spray deodorant, a bowl of water, and liquid soap. It's a pretty simple experiment -- you just pour some dish soap in the water, stir it, then spray the deodorant can while submerged in water. The final step is lighting the burning bubbles on fire. Yeah!

How To: Find dinosaur fossils

Where do you go? How do you know how to look for fossils? How about dinosaur fossils? That's a very good question, and the Museum of the Rockies has the answer, along with Mark B. Goodwin, Ph.D., Assistant Director of the Museum of Paleontology at the University of California, Berkeley.

How To: Make a storm inside a test tube

This science experiment will show you how to make a storm inside a test tube. This video tutorial will demonstrate the process of making the miniature thunderstorm inside a test tube with just a few common chemicals. All you need for your very own thunder storm is a glass test tube with holder, sulfuric acid, ethyl alcohol (ethanol), potassium permanganate, glass dropper, measuring spoon, and please wear safety goggles. Sparks and pops occur completely random, just like in a real thunderstorm!

How To: Make money burn green

This science experiment will show you how to make money burn green. This video tutorial will demonstrate the process of making the buck flame green, without damaging the bill. All you need to get that green flame from your green dollar bill is some Heet (methanol), a glass beaker, boric acid, and a measuring spoon. The combination of these chemicals emits a green flame. This is a new twist on the famous "non-burning dollar bill" trick.

How To: Turn a penny into gold with common chemicals

This science experiment will show you how to turn a penny into gold with common chemicals. This video tutorial will demonstrate turning the copper penny into a silver penny and into a gold cent. All you need to make gold pennies is sodium hydroxide (also known as lye), zinc powder, a small glass beaker with some distilled water in it, a clean copper penny, a couple of measuring spoons, and a glass stirring rod.

How To: Make a simple rocket with film canisters

Try out this science experiment... watch this video tutorial to learn how to make a simple rocket with film canisters. This is purely educational, and demonstrates the reaction of an Alka-Seltzer tablet, toilet paper, and water. If you don't have Alka-Seltzer, you can substitute it with baking soda, then substitute the water with vinegar.

How To: Build a real lava lamp

This is how to make a near professional grade lava lamp. We did this as a chemistry project. We perfected it in a week. This took many hours to do, as we had to get the density just right. We remade it three times, also. At the very end, we combined all of the wax into a huge flask. And then it blew up.

How To: Make a wax and Coke explosion

Watch what happens when Coke is mixed with wax. Learn how to do this cool science experiment yourself. Can anyone explain the science behind this??? You will need Coke (diet or regular), a glass test tube, and a candle. Break off a chunk of wax from the candle, put it in the test tube, heat the test tube until the wax is boiling and then quickly add to the coke.

How To: Make blobs in a bottle with a Lava Lamp effect

The World's Easiest Lava Lamp! This is an easy, fun science activity that is great for any age. In fact, our video crew ended up taking the extra bottles home to show their friends. It is also a great demonstration of liquid density, the release of gases in a chemical reaction, acids and bases, intermolecular polarity, and well, just plain science coolness.

How To: Make an amazing floating static orb

Learn how to make this spooky, amazing floating static orb. This is so simple, and so cool. It uses static electricity to make a tinsel orb levitate above a PVC pipe. We've gotten the orb to float for over 10 minutes. We just discovered you can use a regular balloon instead of the PVC pipe, but we like the pipe best. Watch the video, and then make your own!

How To: Make extremely simple scales with a 9v battery and cap

Watch this video tutorial to see how to make extremely simple scales. This scale is useful when you want to weigh small portions of a substance (like a few grams of powder). It is difficult to get real weight using these scales though. To make this homemade scale, you'll need a plastic bottle cap, a plastic bottle or box, a 9v battery, clear sticky tape, glue for the plastic (epoxy or fast-hardeneing), scissors and a screwdriver.
