Television’s best bets for Wednesday:
On the summer series “Penn &Teller: Fool Us,” aspiring magicians try to baffle the veteran duo with a single trick. If neither Penn nor Teller is able to explain how the trick is done, the contestants win a spot in their Las Vegas show. 8 p.m., The CW.
Just when you thought it was safe to go back in the water (or take a stroll in Times Square), here comes “Sharknado 2: The Second One.” It’s the fin-tastic sequel to the low budget flick that whipped up a surprise social media storm last summer. 9 p.m., Syfy.
