This amazing experiment demonstrates how atmospheric pressure will push an egg into a bottle. A great science experiment for children. Suck an egg into a bottle.
*WARNING* This experiment uses heat and boiling water, so be sure to have an adult around to help. This classic experiment is a fun way to learn about air pressure. We don't usually think much about the air around us, even though it plays such a vital role in our lives. it gives us oxygen to breath, carries away excess heat from out bodies, and squeezes us with over 30,000 pounds of pressure. Wait a minute! What was that last part?For this experiment, you will need:
This week's experiment has made the rounds through the Internet as a strange trick, but there is science here too. We are going to use the science of complex systems to confuse your body. To try this, you will need:
Can you guess which household liquids sink and which ones float? Play along with the A-TV science team in this video lesson!
The only thing better than successfully pulling off a new experiment is doing it with household materials. You get to laugh in conceit as professional scientists everywhere spend all their grant money on the same project you just accomplished with some under-the-sink chemicals! However, there are times when DIY gets dangerous. Some household chemicals are not pure enough to use and some are just pure dangerous. Let's take a look at two problems I have encountered in the course of mad sciencing.
Soap suds aren't just for dishwashing! Blow away your family and friends with this cool science experiment.
In photography, using filters over lenses is a common practice and provides a great way to set the mood or to create an artistic image. The only problem is that they can be quite costly and there currently aren't many available for cell phones specifially. Fortunately, there is a simple solution to this, and all you need are everyday objects that can be found around the house. If you're a purist and don't want to rely on filters provided by camera apps, this is a great way to experiment with ...
Who could resist a gummy bear? Those rubbery little candy creatures shaped like a bear are just too cute and too delicious to pass up. If you can't get any enjoyment out of those gelatin-based confectioneries, then you're simple not human. Even scientists love them, but not for their seductively sweet properties...
What happens when you combine 200 liters of Diet Coke and over 500 Mentos mints? It's amazing and completely insane. The first part of this video demonstrates a simple geyser, and the second part shows just how extreme it can get. Over one hundred jets of soda fly into the air in less than three minutes. Do the diet coke and mentos experiment.
Humming while beatboxing is one of the most important techniques to pick up if you're planning to cover popular songs. It's also a key element for singing and beatboxing, but that's for another tutorial. Here, I'll teach you how to hum while beatboxing by explaining exactly how it works.
Last month, mobile application consultant Jonathan Stark unleashed his Starbucks Card to the public as an "experiment in social sharing of physical goods using digital currency on mobile phones." Basically, he purchased a Starbucks Card and registered it via the Starbucks Mobile App for iPhone (there's an Android one, too) which allows caffeine addicts to pay for coffee and baked goods with their mobile device. He then took a screenshot of the barcode and let anyone on the web download it for...
Watch Monty Don as he experiments with a new method of growing summer-fruiting raspberries, which claims to yield fruit in the first year.

Love mangos, but never got around to eating fresh ones? Are you addicted to mango juice and mango yogurt? Well, nothing beats the fresh test of a real, freshly cut mango, so you have to go out and get some, but before you do, you're going to need to know the proper way to slice and dice these fruity beasts.
If you're the kind of person who frequently does science experiments at home, you probably have a hot plate. But if you're more of an occasional amateur scientist (or just don't want to buy one), it's much easier to hack your own.
Welcome to the Mad Science World! Hold onto your radiation-shielded hard hats—we're going to be posting a ton of great how-to articles and videos every week, showcasing the maddest of the mad science experiments on the web. We hope you will be inspired to try these projects at home, but always remember—safety first!
An experiment was carried out at our laborataries to investigate the flow through two pipes of same diameter fitted at the same height from water level inside of a water tank as shown. It is found the longer pipe line inside the water tank generates a higher speed resulting more powerfull flow. Flow in this pressure pipe develops due to gravitational accelaration on a horizontally flowing water column also, when it is an enclosed stream of flow. If this length is short it is not possible to d...
Recreating one of Will's mad science experiments, I made some potassium nitrate crystals. This was definitely the most fun part of my DIY smoke mix. I can't win the contest, but I'm just putting it up here for fun, since I liked the pictures so much.

just experimented to wear those eyeglass which are partially concave and convex no editigns and mixings in this
An old wooden horse head keychain fell to its demise in my candle. Took the opportunity to finally use the Camera+ app on my iPhone 4. I haven't really used it until today, so I guess I'm just playing around at this point... experimenting.
Well, it has already come to this. Minecraft is now an educational experiment! Go check out the site above for more info.
Just stumbled across Mozza's new cookbook, authored by Nancy Silverton, co-owner (along with Mario Batali & Joe Bastianich) of the famous Los Angeles restaurant/pizzera. Silverton is also founder of the La Brea Bakery.
Below, the latest from Cyriak Harris. This one's called Baaa, and it's just as mystifyingly odd as Cyriak's past work. Lamb conveyor belt? Multiplying ovine spewing from a gaping, undefined sheep orifice? You will never look at the ovine race the same way.
