CES – the huge annual technology show in Las Vegas – gets underway on Tuesday. But ahead of the official opening of the show, tech companies are showing off what they’ve got this year. Of course there are the crazy gadgets like a garbage can that will tie bags closed itself when they’re full, a showerhead with Alexa enabled, and a cat feeder that can read a microchip to dispense the right amount of food. Also on the agenda this year is lots of 5G tech, thinner/bigger TV’s, sex tech, and new innovations for smart assistants like Alexa. Alex is attending a reporter preview event on Sunday night and can tell you what else is on tap and will play sound with those showing off their goods. ABC's Alex Stone is there and joins Tony with a breakdown.
