Here is a video that shows 90 seconds that could save your life. How to actually MAKE A FIRE with a lens, rather than just burning a hole in a leaf. (Or frying ants, which seems to be the other thing that kids like to do with magnifying glasses.)

An amazing science trick with smoke and a flame. Try it at home.

When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. When light passes from one material to another, it can bend or refract. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts.

A simple method to test any alkaline battery in seconds! Works on AA, AAA, C, D batteries.You can separate good from bad.

In this video tutorial I will be explaining how to work a tension problem. Usually these problems are found during a Newtons laws unit in physics. I am currently in physics and I thought I might share my strategy and work to help you guys succeed in the problems. Thank You. The video was made with Explain Everything. Also, please check out my youtube channel. It is new and I pasted a link for you guys to check out. Like comment and subscribe!

Watch this science video tutorial from Nurd Rage on how to make hot ice with Dr. Lithium. This is the complete guide to making hot ice, more correctly called sodium acetate. See how to create it, fix it, and use it. All methods from baking soda and vinegar to laboratory synthesis are shown.

Homopolar motors tend to be typecast as simplistic in nature, and that's true for the most part. The bare minimum requirements are a battery, conductor, and magnetic field, but when it comes to Valentine's Day, they're nothing short of complex.

Creating awesomely messy slops of DIY slime and curdled fake blood isn't something new—we even have guides on making Dr. Seuss-friendly Oobleck and the radioactive green ooze that created my childhood favorite Teenage Mutant Ninja Turtles (minus the radioactive part, of course).

Quick and easy science trick called the leidenfrost effect. Imagine that the water droplets are genies or indians riding on a magic carpet.

I have created this geometric puzzle for your own personal enjoyment. Why not stimulate your mind and give it a little workout? There is also a solution video to check your answer or find the answer.

Static electricity might seem like magic but you don't have to be a wizard to get rid of it. There are simple steps you can take to reduce the amount of static electricity in the air or on you by using some items you probably have at home.

mind blowing maths trick.

I will guess your phone number and age in one minute.

Hi There! I Recently Made a Bowl Out of Buttons & Glue by Gluing the Buttons on an Inflated Balloon Then Painted 4 Coats of Mod Podge Over It, Letting It Dry Between Coats. Once It Was Completely Dry I Popped the Balloon & Found That the Bowl Is Still Soft & Flexible. I Don't Have Much Money So I Am Looking for a Homemade Substance I Could Coat the Bowl with That Is Clear & Will Sturdy It Up a Bit, Maybe Resin or Plastic-Like or Anything That Dries Clear & Hardens. Does Anyone Have Any...

Cool Science Experiment with water and Cooking Oil.

Most of the time, when I'm bored during math class, I play with my calculator to satisfy my boredom. Recently, I've discovered that when multiplying any number by 11, 111, or any number similar to it, that it has a pattern (though I guess everything in math has a pattern). I don't know if this technique is original, because I didn't read anything about this. It's just mere observation. If it's a tried and true technique, let me know.

If you've ever used a heating pad or hand warmer, you essentially know what "hot ice" is. It's supersaturated sodium acetate, and it's actually fairly easy to make at home out of sodium acetate crystals. You can also make it out of vinegar and baking soda (directions at the bottom of this article).

Physics can be a real mind bender, but this educational video will show you how to wrap your head around Heisenberg's uncertainty principle. And no, that's not the same Heisenberg that's in Breaking Bad. We're talking about the famous German theoretical physicist Werner Heisenberg, someone whose work you'd be more likely to see in Fringe.

There's no reason to wait for Halloween to play with dry ice. It definitely creates a creepy fog-like effect when you add a little water to it, but there are some other really cool things you can do wit dry ice. Here are just 5 non-Halloween ways to use dry ice for tricks or pranks.

In this video, I will show you how to make copper glow red hot with the catalytic oxidation of acetone. For this science experiment, we'll just need some acetone, copper wire, and a flame source to initially heat the copper coil we'll make.

In this video, I'll be demonstrating how anyone can make their own iodine clock reaction with simple over-the-counter chemicals.

Blake Had a Total of $3400 to Invest in Two Accounts. One Account Earns 6% Simple Interest, and the Other Account Earns 8% Simple Interest. How Much Should Be Invested in Both Accounts to Earn Exactly $234 at the End of 1 Year?

In this guide, you'll learn how to make your own boric acid from borax and other common chemicals to produce a green flame when mixed with methanol.

This HowTo is about using Pattern Blocks in the classroom. All you need is a classroom set of pattern blocks and a camera. Each student or group of students is given a set of pattern blocks and a time limit. The assignment: make an artwork that illustrates the concept of symmetry, small enough to fit on a single student desk. When the art is finished, take a photograph of it and then let the students vote to choose their favorites.

This slime is toxic-free and can be used as either a kid toy or to make a great prank. This slime can be made in just a few minutes and doesn't require much for materials. Our video explains in detail how to accomplish this project with step-by-step instructions.

It's a great science project

In this Quick Clip, I'll be showing you how a supercooled soda is transformed into a slushy "slurpee" in under 4 seconds. I was inspired to do this little soda trick by The Super Effect's video on YouTube from a few years ago.

i can guess exact date and month of your birth day.bet and win with anyone using this trick .it never fails.you can attract your colleagues and classmates with this trick.

beautiful mathematics .amazing shaped hills with numbers formed in multiplication.watch it and show it to the children and students to make them interesting on mathematics.

In one of my previous articles, I showed off how to make water freeze into ice instantaneously. In this article, I'd like to elaborate on this, and show how a glass of water can turn to ice instantly on command. What exactly is this supernatural power? Discover the secrets to ice-bending—in real life.

Sure it's been done before, but it never gets old. There's something magical about dry ice, bubbles, and especially the result you see when they're combined!

How heavy is a plastic bag? Not very heavy at all, but in order to use a plastic bag to help me karate chop a thin wooden stick, I don't need weight—I need air pressure. Below, the "Quick Clip" demonstrates the power of air pressure via the vacuum created between a plastic bag and the countertop.

Have you ever seen water freeze instantly? This "Quick Clip" shows some of my personal experiences with making instant ice using a bottle of water supercooled in a freezer.

hi friends can anyone explain me how to solve problems based on installments as an example i have a problemwhat annual installments will discharge a debt of rs 1092 due in 3 years at 12% simple interest.

i tried making hot ice numerous times with sodium acetate tech anhydrous and failed. plzzzzzzzzzzz help!! can u give me exact measurements and directions on how to?
