This episode of Shark Tank features a battery charger made using fire and water, a service that helps people find and fire music instructors, a way to stop accidental fire sprinkler activations, and all-inclusive project kits.

Taylor Robinson Music

First into the tank is Taylor Robinson with his business, “Taylor Robinson Music.” He is seeking $100,000 for a 10 percent equity stake in his company. His business is an innovative service that connects students and teachers where people can search for and book instructors through his website or app. His business has made $2.5 million in the past six years. Last year the business made $450,000, but only $40,000 a year in profit. There are 4,000 instructors currently listed on the website.

Robert Herjavec and Mark Cuban thinks he is close to getting his business moving in the right direction, but not quite there yet. Daymond John thinks he is working “hard, but not smart.” Lori Greiner believes it would be tough for her to pitch the business to QVC, so she’s out. No Sharks take the bait, and Taylor exits the tank without a deal.

Powerpot

Next up are David Toledo and Caleb Light with their business, “Powerpot.” They are seeking $250,000 for 10 percent equity. What if you could charge your phone from a pot of boiling water? Their product does this. The PowerPot is a portable thermoelectric generator that produces electricity while you cook. Use it to charge cell phones, power lights, and more. They have sold $300,000 worth of Powerpots this year.

Daymond doesn’t see the market for the product, and Lori sees the company in phase too early to invest. Mark likes what they’re doing, and offers $250,000 for 20 percent. They see a lot of value in Mark, but counter with 12 percent equity and 3 percent in advisory options. Advisory options are a separate poor of stock set aside for investors who add strategic value. Mark takes the deal and David and Caleb leave the tank with an investment.

Update: Ava the Elephant

On the very first episode of Shark Tank, Tiffany Crumans brought a prototype of her children’s medicine dispenser “Ava the Elephant” and made a deal with Barbara Cocoran. Barbara got her business connected with Healthpons, who made purchase orders of over $6 million.

Fun Time Express

Up next are Stan Krozel and Kevin Ullery with their company, “Fun Time Express.” They are seeking $125,000 for a 20 percent stake in their company. It’s a trackless train ride that kids can ride on at the mall or amusement parks. In 2012, they made $216,000 in gross sales.

Mark believes it’s not a scalable business, and believes it would be tough for the business to grow. Kevin and Robert think the business is too small. Lori likes what they’re doing, bringing something to the mall that’s different.

After a few Sharks drop out, Stan and Kevin revise their offer. They are now willing to do $125,000 for a 20 percent stake with 100 percent of profits used to repay the investment. This interests Lori and she offers half and convinces Kevin O’Leary to put up the other half. Stan and Kevin happily accept and have a deal with two Sharks.

Quickstop Fire Sprinkler Tools

Last into the tank firefighter Matt Scarpuzzi with his business, “Quickstop Fire Sprinkler Tools.” He is seeking $150,000 for 10 percent equity. His product is a tool that stops sprinkler heads after they’ve been activated, to limit water damage.

Kevin thinks he will have to educate every potential consumer on the product. He has sold $18,000 in the last six weeks. Matt then takes out another product that stops pipe leaks, but the Sharks don’t seem impressed. The Sharks believe the biggest challenge is educating people on the product. Kevin thinks the product is perfect for QVC, and Lori believes so too. She offers half at $75,000 for 18 percent, but wants to go in with another Shark for the other half. Robert likes the design, but doesn’t see a self-evident consumer market.

Kevin says he will only do the other half of the deal with Lori if he gets 25 percent. Lori tries to talk Kevin down to 40 percent, but he won’t budge. The offer on the table is Lori and Kevin offering $150,000 for a 50 percent stake. Matt is not willing to give up half of his business, and declines their offer.
