The pressure underwater is undeniably strong. If you were to fill a balloon with water and take it underwater, it would not burst but would stay the same size because liquids are not compressed. The pressure is the same, inside and outside of the balloon. If you were to fill that same balloon with air instead, the lower it dives into water, the more it shrinks, until it eventually can't take the pressure anymore and bursts.

Growing up, my family would get together in the living room every Saturday night and gather around my mom's old boombox radio and listen to Disco Saturday Night on 104.3 FM from 6 p.m. to 2 a.m. (the show ended in 2008 after 14 years of consecutive shows). The old ladies in the picture below are the best representation of these nights that I could find. Now, the radio is all but dead (just like the old ladies above) in this world of music streaming services and torrenting. All of our music is...

A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.

You may already know that you can build a functional circuit on a sheet of paper with the graphite from a pencil, but you'd probably never think of using it to fix an electronic device. This same principle can be used to bring back a bricked phone, but can also repair a damaged or corroded trace in a printed circuit board. Redditor 404ClueNotFound spilled water on his favorite computer keyboard (like so many of us have done before). The damage was minimal, but after drying it out, one key sti...

Most of us have traded our desktop systems for laptops, tablets, and mobile devices, meaning there's a lot of outdated hardware sitting in attics. Want to give your old computer a new purpose? Matthew Chappee turned his iMac G4 into an HDTV using the guide by Dremel Junkie. One thing to note before you take on this project yourself is that if you want to use it to watch cable, you'll need a converter box to get around the MPAA's HDCP restriction. But, a converter box is considerably less expe...
In this tutorial, we learn how to increase the power of a 5mw green laser pointer. First, you will need to gather the parts you will need, which include a vise, the laser, a soldering iron, and a block of wood. After this, cut the block of wood in half and then put your laser pointer in the middle. Pull and twist so the module comes out, then pull the foam protector off. Don't lose any small parts that come out. Next, unscrew the silver cap and then put on your new laser module. Replace all p...
An EMF detector will help you find invisible electromagnetic fields, and you can make an inexpensive one for under ten dollars. This will only detect the presence of a field, you will need other tools to be able to measure its strength.
Now this is one how-to video you probably don't come across often. While most jewelry makers and welders probably purchase their soldering irons, it's actually possible to make your own soldering iron out of graphite pencil, car battery and jumper cables. We know it sounds like you're going to end up lit up like those much-parodied dads trying to set up Christmas lights on the rooftop during the holidays, but this process actually works quite well.

It may be intended as a toy, but this gizmo can be hacked for more than just watching a remote-controlled car's video spy cam. This HUD (heads-up display) comes with the Wild Planet Spy Gear Video Car, but it's said that you can purchase the video headset separately. And it's not really a HUD, because you can't see through the video images, but it's close enough to be handy for all sorts of things, like computers, iPods, robots, wireless cameras, and gaming. Who wouldn't like to Call of Duty ...
