Like theme music, I always feel that I need more fog in my life. Fog can be useful for many reasons—warding off smaller siblings from your bedroom, keeping curious hands out of your cupboard, and tricking your friends into thinking there's something horribly wrong with their vehicle. So, today we'll be making a very simple fog machine for small scale applications.

I love making my own printed circuit boards. It really gives a professional look to a finished project, and having all the design files means I can whip up another batch whenever I need to. However, when I need to make, say, three thousand swarmbots or fill an order for a dozen PCBs, the traditional etching process can slow down the operation to a crawl.

The best chemistry experiments are those you can perform with items already laying around your house. With only some sugar, salt substitute and an instant cold pack, you can make your very own gunpowder! Being able to make homemade gunpowder without a trip to the store can be a lifesaver, no matter if it's just for testing out a Civil War-era musket, blowing up stubborn tree stumps, or preparing for battle when imperialists overrun your country.

Simple items from around your home can create an amazing effect. The Iodine Clock Reaction.

There is something special about a secret knock. It gets you into secret super villain meetings and is a surefire way to test for rotating bookcase passages. Secret knocks usually work with an intimidating drug lord and for policeman listening at the door for the correct pattern of raps.

This is a easy tutorial of Pepper expansion.Hi I am dheeraj this is a mad science tutorial this is very easy I'll tell you more of experiments lets start .Before starting how does this work this actually it works on principle of surface tension. Surface tension holds the surface molecules of liquids tightly. So the pepper particles when soap applied , they get moved when molecules are Holden tightly.Lets Do this :D

As you read in the heading this is simple compressed air cannon which you can build with PVC pipes from your local hardware store for a couple of bucks.

In this video i wanted to show how the railway signal works. Sorry for a poor quality, this is my first video on youtube. Interesting thing. When train is approaching to the road crossing, signal immediately turns on. The secret is that there is a signal coming through the rails, and when train is near, it close this signal and siren starting work.

Grab a cup, a pair of scissors, a black marker, a box of matches, a plate, and a few tea bags. Open a tea bag and pour the contents into a cup. Use the scissors to cut the empty tea bag in half. Now with the marker give your tea bag a ghostly face. Place your ghost on the plate standing up and light a single match. Light the top of the ghost and watch your ghost take flight!

In theory an egg shell works similar to the enamel found on your teeth. Grab a can of Coke, an empty jar, and one delicate egg. Place the egg within the jar and pour the coke over the egg. Store the jar in a safe place for one day. Once twenty four hours have passed, open the jar and pour the soda into a bowl slowly, leaving the egg in the jar. Gently remove the egg from the jar and examine what the soda has done to the shell. Remember the egg represents the enamel on your teeth!

Grab a glass jar with two lids and 50% alcohol. Pour just enough alcohol to coat the entire inside of the jar. Put a lid on the jar and shake it around to get the alcohol to spread all around the inside. Grab the second lid and make a hole in the middle of it. Replace the lid with the lid you just made a hole in. Take a match from a matchbox, strike it and place it near the hole in the lid. Enjoy the reaction!

In this experiment, you will need a single egg, thongs, a lighter, and a cup filled with water. Grab the egg with the thongs. Now with the lighter, start burning the egg to create soot all around the egg. You will end up with a black egg. Grab the cup filled with water and gently place the black egg into the water. You went from a white egg, to a black egg, to the end result of a silver egg!

Setup: Grab a matchbox and three matches. Stand the matchbox on its side. Sandwich a single matchstick between the insert and the cover. One on the left and one on the right. Between the two matches, add the third match.

Setup: Grab a matchbox and a small coin. Sandwich the coin between the insert and the cover.

The Setup :

In this experiment we used lots of short ball chains and connected them all. *Note - if you don't have tons of ball chains, you can use Rigatoni pasta and pass a rope through them connecting them all. You can even color them different colors for an added effect too!

Get your hands on as many pencils as possible, the more the merrier! Go ahead and sharpen all of them to a nice sharpened point. Then get a ziplock bag and fill it with water. This is where it gets interesting, start on one side of the ziplock bag and put the pencil through it so it comes out from the other end. There is a trickle of water at times but the majority of the water will not spill. See how many pencils you can put through the ziplock bag!

Are the kids bored? Need something for a school project? Want a great activity for a family night? In this tutorial I am going to show you how to make slime! This easy slime recipe only requires 3 basic everyday household ingredients, with an optional 1 or 2 more ingredients. The slime is non-toxic and super safe to play with. Don't eat it though! So let's get to it, let's make some slime!

Kid friendly experiments using color to show different reactions!

In order to be considered alive, an object must have these traits.

Facilitated diffusion is a type of passive transport in which a cell can move larger objects into and out of the cell.

I want to know about making duplicate rice puller coin

Whether you've got an itch for a mini-flamethrower, a shower of burning sparks, or a exploding ball of flames, these little fireworks-producing lighters may be the answer to your pyrotechnic cravings!

i want to know how to make an home made electrode to measure eeg

How to charge original iridium coin to pull rice like a magnet. What chemicals n procedure r used to make duplicate rice puller

hello , can you help me please to find a circuit for my final year project i'm working in a project to transmit video and audio by using LEDs light

I would like to make the explosive polymerization with p-nitro aniline and sulfuric acid. I work in a laboratory and have access to the chemicals. I have seen several videos on Youtube and it looks awesome... When I try nothing happens, even after 10 minutes of heating. I have mixed 2 sp of the aniline and approximately 1 ml acid. I heat with a bunsen burner. Any good suggestions why it won't work? Best regards Jørgen

Whether you're in an airport, restaurant or waiting room, the insidious grip of televisions on human life is omnipresent. Sometimes it's nice to talk to other human beings while looking at them directly—actually hearing what they have to say.

I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it. Whether you want your robot to terrify your enemies with a demonic synthetic voice, you just need a pocket boom box on the go, or you want to a miniature guitar amp, a simple LM386 amplifier can crank up those signals loud enough to play through any speaker.

If you've got a birthday party to plan for a young budding scientist coming up, a little nitrogen should do the trick. In this project, I'll show you 10 "super cool" tricks with liquid nitrogen that you could try, but probably shouldn't!

Carving pumpkins into creepy looking jack-o'-lanterns for Halloween can actually become fairly boring and tedious if you're doing the same thing year after year. This time, jump into a whole new realm of Halloween fun with some exploding pumpkin faces! I like to call them blast-o'-lanterns, but can call them whatever you want.

How to make a Science Investigatory Project about Electricity

Home chemistry is great, but what happens when you forget to label your chemicals? How do you know if you turned a clear glass of ammonia into a clear glass of unobtainium? Chemists have a tool for just that.
