'Shark Tank': A rabbi impresses Mr. Wonderful [Exclusive video]

Yahoo! TV

The best ideas are almost always the simplest ones on "Shark Tank," and that's proven true once again on this week's episode, when an entrepreneurial, iPad-lovin' rabbi wows tough-to-impress shark Kevin O'Leary.

Rabbi Moshe Weiss, as seen in the clip above, loves his iPad but is frustrated by the fact that the speaker faces away from him. His solution: the SoundBender, a little piece of molded plastic that makes a big difference in the sound quality of the Apple tablet.

The performance of the SoundBender is impressive enough. But when Rabbi Weiss tells O'Leary, aka Mr. Wonderful, that the gadget costs just $1 to make and retails for $12.99, Mr. Wonderful thinks it's a gift from above.

"A high power's involved," jokes O'Leary.

"Shark Tank" airs Fridays at 9 PM on ABC.
