Episode 5 of America's Got Talent 2013 will feature a family of acrobats, a human jump rope, a wavy-armed man and a life-threatening act involving a flaming bottle of gasoline, according to NBC's preview.

"Chicago is on fire!" host Nick Cannon says at the beginning of the promotional video for the episode. The narrator touts America's Got Talent as the No. 1 competition show of the summer explaining that the talent this year is "so big, and so raw, it'll throw you for a loop."

The most significant portion of the promo features a man putting a flaming bottle of gasoline on top of a floating balloon and then popping it. Judge Heidi Klum ducks for cover while judge Howard Stern says, "You're the first guy to come out here and risk my life!"

As for last week's acts, many clips from the episode were uploaded to YouTube and it has been revealed which ones were more popular with the public. Aaralyn, the 6-year-old metal singer, received the most views over the course of the week, getting over 10.5 million. She has become the most viewed act of this year's competition yet.

Coming in at a very distant second this week was opera trio Forte, who received over 187,000 views. Right behind Forte was tap dancing-meets-hip-hop act Hammerstep with over 170,000 views.

Jacob Calle, who put a scorpion in his mouth while trying to blow bubbles, got over 167,000 views despite not being sent through to the next round. Rounding out the top 5 was the young Struck Boyz whose hip-hop moves were viewed by over 134,000 people.

Stats like this may be good indicators of which acts America will be interested in voting for in the coming rounds, though there are obvious exceptions. The novelty of such acts as Aaralyn, while interesting, may not translate to votes in later rounds. Plus, Calle didn't even make it to the next round, so his YouTube views have no lasting effect on the competition.

America's Got Talent will air its two-hour fifth episode of the season Tuesday night at 9 p.m. on NBC. Watch the fourth episode of America's Got Talent 2013 in its entirety here:
