You may think you've seen these before, but you haven't. Although traditional clear soap bubbles give you a rainbow effect in the right light, Zubbles are the first truly colored bubbles-nearly opaque, with a single vibrant hue. The problem, which took Minnesota toy inventor Tim Kehoe more than 10 years to solve, was to create a dye that could not only tint the thin wall of a soap bubble but that wouldn't leave a stain when the bubble broke. His solution: invent an entirely new dye that simply disappears.

Pumping beer too quickly leads to excess foam, so bar patron turned inventor Matt Younkle designed the TurboTap to reduce the turbulence of fast-flowing beer. The tap's tapered interior limits the beer's acceleration, and an internal diverter sprays it across the bottom of the glass. The result-now available at ballparks and bars-is a perfect pour in half
the time. $100

Most complex events in today's computer games-a stack of boxes tipping over, an avalanche-are just prerecorded animations that give you the same outcome every time. But design a game with physics processing, and suddenly it's like the real world: The boxes fall differently depending on how they're hit, and the avalanche may or may not knock you off the mountain.

Imagine having a 10-gigabyte hard drive in your cellphone or a terabyte of space on your laptop. Perpendicular recording, a new way of writing data to
a hard disk, creates the possibility for these kinds of capacities, just as we're approaching the physical limits of traditional recording methods.
Hard drives store information by changing the polarization of microscopic magnetic bits aligned end-to-end on a surface called a platter. But you can pack in only so many bits before they interfere with one another, randomly switching orientation and turning your data into noise.

With nine processors and 234 million transistors, the Cell is the powerhouse of Sony's forthcoming PlayStation 3 console. The four-plus-gigahertz (depending on its application) chip calculates an unmatched 256 billion operations per second, making it 35 times as fast as the PS2's chip. The upshot: Characters react more realistically (like flinching when bullets whiz by). Next year Toshiba will offer an HDTV set that uses the chip to decode high-def signals.

A Fuel-Cell Motorcycle With Portable Power
Riding the ENV is more akin to skiing or sailing than cruising on a 176-pound motorcycle. It's emission-free and as quiet as your computer. At the heart of this hydrogen-powered machine is a fuel cell, dubbed the Core. It breaks down hydrogen into electrons, which power the electric motor, and protons, which interact with oxygen taken in through the ENV's nosecone and are released as Earthfriendly water vapor and heat. The Core is detachable, so it can power a small house or boat. Available in late 2006. $6,000

It looks like Bubble Wrap, but BlastWrap isn't for cushioning eBay shipments. A BlastWrap-lined garbage can will dissipate a backpack-size-bomb blast in less than one thousandth of a second. The wrap's 2.75-inch compartments are stuffed with heat-treated perlite (the foamy pellets found in potting soil), a volcanic glass. The beads have a strong internal structure of sealed, air-filled cells. When a blast occurs, the cells are crushed one by one, minimizing damage to the surrounding area, while fire extinguishants snuff the fireball.

HDTV sets are stunning—until you pop in a movie and are reminded that DVDs are not recorded in high definition. At 480 lines of resolution, they don’t even begin to take advantage of a 720- or 1,080-line display. That will change later this year when Toshiba introduces the first high-def disc player for the U.S. market. Toshiba’s breakthrough box, an HD DVD player that at press time was still unnamed, will cost about $1,000 (toshiba.com).

First there were big screens. Then big flat screens. Now there are big flat screens packed with tricks, like the ability to record TV or access your home network. It’s all part of the push to minimize the number of decor-busting black boxes while maximizing entertainment choices—movies, slideshows, your music collection. Here are five reasons to chuck your TV in favor of a multitalented model.

1. The Laptop Impersonator
This 2.7-inch-thin flat screen takes its cue from the computer world, with two PC-card slots to handle its latest features.
