One of the only things I remember from watching Nickelodeon as a kid is the epic green slime. Looking back, I don't know what was so great about it, but every kid my age thought that being drenched in slime would be the coolest thing on earth. Of course, the first thing I did was beg my parents to buy me some fake slime, but I never knew I could've easily made my own at home. One of the most common ways to make slime is to combine liquid glue with water and a household chemical called borax. ...
Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
In this tutorial, we learn how to make hydrochloric acid from salt. First, you will pour some salt into a distil flask. After this, you will add in some concentrated sulfuric acid to the salt. Next, you will let these react with each other. You will start to see gasses bubble up and the excess hydrogen chloride gas come out through the top of the tube. To create a stronger reaction, you can add heat underneath the reaction. Then, test this by exposing it to ammonium chloride. If it's the righ...

Here we will demonstrate how to measure the volume of a balloon. A balloon is not a straight edged polygon shape, usually, so the mathematical equations get that much harder, on the flip side, it may be a spherical or ovalish shape, but measurements with math alone are detrimental due to the uneven sizes of the balloon. Here is how to do it properly. You will need a bucket, preferably, to hold water, a larger container than your original bucket, and a measuring container. Place the bucket ins...
310tutoring shows viewers how to easily convert Grams to Moles for Chemistry. If you have 120 grams NaOH and we want this in moles we need a periodic table. Now, you need to figure out what the mass is of each individual element in NaOH. You need the mass of Na, O and H. Na mass is 23, O has 16 and H is 1. Add all of these up to get the molar mass of NaOH is 40 g/mol. Now use this to convert 120 g to moles. Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel...

No, we're not lying. But before you try and tear a plain old penny in half, you should probably watch this video first or you may hurt your fingers. While ordinary pennies are very, very difficult to rip, if you get rid of the zinc core you are left with only the thin copper shell, which is itself very easy to tear apart.
A balloon's worst fear is a sharp object, so usually when you puncture a balloon, it pops in your face. Not with this science trick! To puncture a fully blown up latex balloon without popping it, you'll need a pointed metal or wooden skewer and some plain old dish soap. That's it.
In this video, we learn how to focus your laser to make it burn. The best spot for a laser to burn things is at its focal point. This is where the beam from the laser is at its smallest. If you hold a match in front of the beam, it will light it on fire as soon as it's in front of it. If you put two lasers next to each other going the same direction, it won't be able to burn because the light beam is too large. If you position the lasers so the light is smaller, then they can catch something ...

Place your specimen into a plastic container with the iodine, then put the top on and let sit, placing your hand under to warm it up. Within a few minutes you will see a violet color vaporizing in the container. When finished, you will be able to take out your specimen and see the fingerprints that are al...
In this video tutorial, viewers learn how to do a sodium and water experiment. Sodium is a silver metal that is very reactive. When exposed oxygen in the air, an outer coding of sodium oxide will form. Simply drop a piece of sodium into a cup of water. When dropped in water, sodium reacts to form sodium hydroxide and hydrogen gas. The sodium will constant move around in the water. Sometimes the heated reaction will cause the nitrogen gas to ignite. Under the right condition, it may even cause...

Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.
