NEW YORK — From a 3-D pen that lets kids safely doodle with melted plastic to an electrically charged glass that makes beer taste bubblier, there was no shortage of fun and quirky gadgets at this year’s CE Week.

The annual, three-day gadget show in New York is meant as a showcase for products coming out for the holidays, though many items are still in development or seeking investments through group-fundraising sites such as Indiegogo.

‘DRAWING’ 3-D SCULPTURES

There’s now a kid-safe version of the 3Doodler 3-D printing pen, which melts sticks of colored plastic into goo that shoots out of the pen tip to create 3-D sculptures. With both versions, the plastic hardens quickly, so you can draw into the air without worrying about your creation collapsing.

The kids’ version 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, half the price of the regular version.

EARBUDS FOR EVERYONE

Finding earbuds that fit comfortably and don’t fall out can be a challenge. 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.

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

FOR BEER WITH AN EXTRA BUZZ

Global Ionics has a glass that uses a small amount of electric current to boost the flavor and fizziness of drinks, be it flavored water, fruit juice or wine.

The current is generated by one AAA battery housed in the base of the glass. The current flows from the glass through its beverage into the mouth.

GAMING WITHOUT SCREENS

ROXs, billed as a “real-life gaming console,” 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.

HD IN 3-D

GoPro cameras are great for action footage, but they don’t shoot in 3-D. Fantem now has a clip-on 3-D lens for it.

Fantem’s Vitrima 3-D lens costs $80 through Indiegogo. The company plans to start shipping them next month and says it’s in talks to get them on store shelves.
