You can whistle while you work. And now, we know, you can whistle while you break a world record, too.
Congratulations to Watts Public School in Watts, Oklahoma, USA, for taking last week's Fan Choice! The record for most people blowing train whistles simultaneously chugged like a locomotive to the top spot, taking nearly half the vote (47.95%) and beating worthy contender Glen Burmeister with the most countries visited by bicycle in 7 days (31.97%).
Watts Public School's achievement will now be entered in our list of contenders for a year-end showdown in which we'll ask you fans to vote for your favorite record of the year at the end of 2013.
Time now to meet this week's candidates and then cast your vote below. This week we'll walk some children to school by bus (it makes sense, keep reading!) and chomp into a nearly 700-pound (almost-320 kg) cake, but we start with a little hula.
LARGEST HULA HOOP WORKOUT (pictured above)
Record: 407 exercisers
Holders: North Lanarkshire Leisure LTD with Powerhoop UK/Innertrak LTD (UK)
Location: Motherwell, UK
That's not all: Powerhoop restricted the event to women as part of a special "Ladies Day Event" celebration. Powerhoop provides padded, patented, weighted hula hoops to be used in fitness workouts.
MOST POP-UPS IN A POP-UP BOOK
Record: 169 pop-ups
Holder: Taichung City pupils and the Taichung City Government
Location: Taichung City, Taiwan
That's not all: The collective art piece took 6 months to produce and involved nearly 300 contributors. The singular book joins together 296 pages that stretch 107 meters (351 feet) long.
LARGEST STUDENTERBRØD CAKE
Record: 313 kg (690 lb) of sweetness
Holder: Team Benns A/C and Tanges Bakery (both Denmark)
Location: Holstebro, Denmark
That's not all: Local master baker Jan Pilmann and his team created the cake to help celebrate Team Benns' 50th anniversary. Literally translated as "student bread," studenterbrød is popular with Danish students for being so inexpensive. It consists of a biscuit base, chocolate-flavored cake layer, and is topped with icing and sprinkles.
MOST PEOPLE UNWRAPPING A CANDY SIMULTANEOUSLY
Record: 614 unwrappers
Holder: The School Wide Activities Team of Tarleton State University (USA)
Location: Stephenville, Texas, USA
That's not all: The School Wide Activities Team (SWAT) organized the attempt to bring university students together in a fun, interactive, and, as they quoted, "unforgettable" experience.
LARGEST WALKING BUS
Record: 1,905 walkers
Holder: Newmarket Schools Together (UK)
Location: Newmarket, Suffolk, UK
That's not all: A walking bus is a traditional method of children getting to school together by walking four across in rows, so as to resemble a school bus while promoting safety. The "bus" route spanned 1.2 km (0.74 miles) and included participants from 10 different schools.
