It may look like a Keurig, but Fizzics isn't for breakfast time...unless you like beer at breakfast. This clever machine uses sound waves to improve the foam and mouthfeel of bottled and canned beers, making them taste more like draft.
Fizzics scored a huge $2 million deal on Season 8 of "Shark Tank." You, meanwhile, can score a deal on the $169.99 system direct from the Fizzics website.
Ugly Christmas sweaters have become a holiday favorite. Tipsy Elves, which scored a deal with Robert Herjavec in Season 5, has turned the new tradition into big business, offering a slew of spectacularly terrible wardrobe options for your next holiday party.
The Elf on the Shelf isn't the only game in town. Neal Hoffman created a fun new Hanukkah tradition with Mensch on the Bench, a book-and-plush-doll combo that teaches children about the Jewish holiday.
This definitely isn't your run-of-the-mill tricycle. Leaux Racing Trikes are legit, high-performance velocipedes with a rear steering handle that lets you drift, glide and perform all sorts of cool tricks.
The Sharks loved the trikes when teenage inventor Tyler Hadzicki showed them off during Season 7, though not enough to secure a deal. That shouldn't stop you, though. You can purchase your own Leaux direct from the company for $350.

Trunkster smart luggage helps make trips just a little bit easier, with a built-in battery (10,400 mAh) to charge devices while you're stuck on a layover. It also tells you how heavy it is when packed, so you can avoid nasty fees for overweight luggage. It even connects to your phone, so you can track it at all times.
Trunkster was a hit on Season 7, when the company landed a $1.4 million investment from Marc Cuban and Lori Grenier. You can buy yours direct from trunkster.co for $365.

Drones are proving to be not only hot gifts but also hot investment prospects. This professional-grade model, plus the promise of a "phone drone" in 2017, set off a massive million-dollar bidding war for parent company xCraft during Season 7.
The GoPro-ready X PlusOne reaches a top speed of 62 mph and has precise hovering capabilities, not to mention the smarts to follow you wherever you go. It doesn't come cheap, though: A build-your-own drone kit starts at $495 at the company's website, with fully assembled models starting at $695.
While you're at it, why don't you help your feline friends defecate as well? Citikitty, a Season 2 sensation, actually teaches cats to use a toilet. (We were skeptical too, but there are plenty of Citikitty success stories on YouTube.)
