This year's CE Week show in New York includes interesting products such as a 3-D pen that lets kids safely doodle with melted plastic to an electrically charged glass that makes beer taste bubblier. The gadget show is meant as a showcase for products coming out for the holidays, though many items are still in development.

The 3Doodler 3-D printing pen melts sticks of colored plastic into goo that shoots out of the pen tip to create 3-D sculptures. On display at the show is a new kid-safe version of the pen, which has no hot parts. The plastic coming out is cool enough to touch. A kids' starter pack includes a pen, an ideas book and two packs of plastic sticks. The kid-friendly set costs $50.

Decibullz touts its earbuds as the first to be both custom and wireless. They are made of a plastic that softens in hot water. The putty conforms to the inside shapes of your ears and hardens in about two minutes. If you don't get it right the first time, just pop the earbuds back in hot water and start over.

The set sells for $120 through the company's website.

Global Ionics has a beverage ionizing device that combines a voltage booster and ionic polarization technology with the human body's energy into a drinking vessel.

Fill any cup, glass, or water bottle with a favorite beverage (including juices, sports/energy drinks, flavored waters, beer & wine). While drinking, your hand touches the metal on the side of the cup. The human body, combined with the voltage booster circuit and a single AAA battery inside the waterproof case, generate a small, safe electric current. Through electrochemical reactions within the beverage ingredients, the number of negative ions from the ionic emitter are enhanced. Once the beverage touches the lip or mouth, millions of negative ions enter the body.

The objective is to provide beverage devices that will speed up recovery due to dehydration, boost energy, flush out toxins, act as an antioxidant, and enhance the body's immune system.

This technology is still in the ideas stage. Global Ionics says it hopes to license it to a beer company or a medical-device manufacturer - for instance, to boost the effectiveness of bubbly flu treatments.

ROXs is designed to get gamer kids active and away from their screens. The kit from A-Champs comes with three ROXs, which look like flat stones about the size of a saucer. You strap them to kids, trees or just about anything else.

Kids can choose one of 10 games.

The starter package is expected to sell for $130 through the company's website. It's expected to start shipping this fall.
