After only a short time, he shows the dramatic change between the portion that was dipped in the solution and the...

How To: Make sodium bromate & potassium meta-periodate

This video tutorial is in the Education category which will show you how to make sodium bromate and potassium meta-periodate. This experiment uses toxic chemicals and releases harmful gases. First you have to make a saturated sodium bromide. To this solution then add a small amount of potassium dichromate. The solution now becomes concentrated. Then make the circuit as shown in the video. You need a 3 - 5 ohm resistor in order to reduce the current. Then let the cell run for around 6 hours. S...

How To: Use ninhydrin to reveal latent prints on paper

In this tutorial, we learn how to use ninhydrin to reveal latent prints on paper. This will work out because you will be spraying a special liquid onto the porous area. After this, you will turn on a black light and then be able to see the fingerprints appear in purple! Be careful with the solution, because it's flammable! This will also stain your skin, so make sure you wear gloves and don't let it contact a surface you don't want stained. To mix the solution, you will combine both of the so...

How To: Solve systems of linear equations by graphing

In this video the instructor shows how to solve systems of linear equation by graphing. A system of linear equation is equations of two lines that are to be graphed on the same coordinate axes. Now take the first equation and write it to form y = mx + b. Now extract the value of slope m and graph the line as shown in the video. Similarly graph the equation of the second line as shown in the video. Now if the two lines intersect at a point, that point is the solution to the system of that line...

How To: Describe a linear system without graphing

This tutorial looks at how to describe a linear system without actually graphing it. In order to do that, you will need to convert both equations of a problem into the Y=mx+b format. Once you have done this, you will be analyzing the m and b values. There are a few rules to follow. If the slopes (or m) and the Y intercepts (or b) are equal, there are an infinite number of solutions (or dependent equations). A second rule is if the slopes are equal and the Y intercepts are different, then the ...

How To: Solve a rational equation with no solution

This is a very interesting mathematical instructional video on how to find rational equation with no solution. How to solve the equation and check the answer. Let us take the example m over m-3 minus 4 is equal to 3 over m-3. In this equation we get m-4m+12 over m-3 is equal to 3 over m-3. When we simplify it further we get -3m +12 = 3. Or -3m = -9 and m = 3. This video teaches you very clearly how to solve a rational equation with no solution.

How To: Use vinegar & hydrogen peroxide to reveal fingerprints

Learn how to find latent finger prints on brass surfaces, such as fired cartridge cases. Called the Acidified Peroxide method, using only white distilled vinegar and hydrogen peroxide that you can find at your local drugstore, you can uncover fingerprints that is usually impossible to see using other methods. After mixing the vinegar and hydrogen peroxide the solution should start turning a greenish color around the brass object after 5 to 10 minutes. After you see the green color throw away ...

How To: Solve a system of equations via the elimination method

Elimination in mathematics is used to find the solution set of a system of equalities. This video tutorial shows how to use elimination to find the solution set of a given equation and offers several examples to illustrate the process. Before applying this method, the equation must be in the form “Ax +By=C.” When graphing a set of mathematical equations that intersect, the answer to the elimination is the point on the graph where the two lines cross.

How To: Easily View Your Current Cellular Data Usage on Your iPhone

If you can't afford an unlimited plan, you're limited to a certain amount of data each month on your iPhone. Even some unlimited data plans have carrier-imposed mobile data caps that throttle the user if they exceed them. Keeping track of your exact usage each day will help make sure you don't get billed more or throttled like a chump near the end of the month.

News: T-Mobile LTE-U Gives Galaxy S8 Owners a Speed Boost in Select Cities

Last month, AT&T made headlines with its disastrous launch of its 5G Evolution network (spoiler alert: it wasn't actually 5G). T-Mobile responded to the embarrassing news by saying the company would be working on its own 5G network, and would take its time rolling it out. Well, T-Mobile may have just pulled an AT&T — T-Mobile is launching LTE-U in the US, and things seem pretty similar to the 5G Evolution's introduction.

How To: Bypass T-Mobile's Tethering Limit for Free

T-Mobile's "Uncarrier" initiative has done wonders for my wallet and my data usage. Before I had to deal with being throttled down to 2G speeds after passing my data limit, but thanks to their unlimited data plans, I'm free to use as much LTE data as I possibly can. The only downside is, when sharing data through a mobile hotspot (tethering), T-Mobile imposes a 5 GB limit (which was recently upped to 7 GB for some).
