Metric Lunch Box
Imagine the insults suffered by the dweeb forced by well-meaning parents to carry this lunch pail to school.The objects children take to school can communicate messages. In the 1970s, the U.S. government encouraged more general use of the metric units of weight and measure, units that had been adopted in almost all other nations. To teach children about metric units, some parents purchased this lunch box.

Hot Chocolate Effect
As defined by Wikipedia:The hot chocolate effect, also known as the allassonic effect, is a phenomenon of wave mechanics first documented in 1980 by Frank Crawford, where the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder. It was first observed in the making of hot chocolate or instant coffee, but also occurs in other situations such as adding salt to supersaturated hot water or cold beer.

The Rule of 87
The frequency of multiple human births follows an apparent statistical "rule of 87." Twin births in the U.S. and European countries happen once in 87 confinements. Triplets are born once in 872 (87x87) or 7,569 confinements, quadruplets once in 873 (87x87x87) or 658,503 and quintuplets once in 874 (87x87x87x87) or 57,289,761. Though the rule cannot be proven for quintuplets, U.S. statistics otherwise follow it remarkably well.
This "Rule of 87" may have been true in the mid-twentieth century, but I'm guessing that the rise of fertility drugs played havoc with it.
I'll also note that the Minnesota Twins won the 1987 World Series. Coincidence?

The science of removing bugs from windshields
When you clean bugs off your car's windshield, think of Detroit researcher Clark Wells who spent his career figuring out how best to do this.
St. Louis Post-Dispatch - Mar 22, 1953
WINDSHIELD-SPATTERING WITH A PURPOSE
The curious actions of Frederick Brownell (left) and Clark Wells at Detroit are in the interests of science. They are using pea-shooter and slingshot to shoot bugs against a windshield at squashing velocity so that Wells, a chemist, can then test fluids to be used in wiper spray to remove them. For his experiments, Wells buys such insects as bumble bees, June bugs, fish flies, deer flies and other of the more succulent species from collectors for amounts up to a dime each.

Huntsville Times - June 20, 1954
Inventor Clark Wells, of Fraser, Mich., lacked the bugs he needed to test out a windshield wiper fluid he was perfecting, so he placed a Classified Ad in a Detroit paper, soon had an adequate supply of bumblebees, June bugs and other insects.

The drift pattern of Nike shoes
In May 1990, five shipping containers holding approximately 80,000 pairs of Nike shoes fell off a freighter during a storm in the North Pacific. About 200 days later, some of these shoes began to wash up on beaches from Canada down to Oregon.But as beachcombers collected and compared the shoes, they noticed something odd. On beaches up north, in Canada and Washington, almost all the shoes were right-footed; whereas further south in Oregon, most of the shoes were left-footed.
Skye Moody explains why this was so in her book Washed Up: The Curious Journeys of Flotsam and Jetsam:
The slight toe curvature of left- and right-footed shoes caused the right-footed shoes to tack northeastward into the Alaska Current, passing the Queen Charlottes along the way, where many beached. Meanwhile, the left-footed Nikes tacked snugly into the southeast-bound California Current, and as it passed Oregon, were caught on an incoming tide.

Oceanographer Curtis Ebbesmeyer co-authored an academic paper about the 1990 shoe spill ("Shoe spill in the North Pacific" -- unfortunately behind a paywall). It also inspired him to start studying other ocean flotsam, such as rubber duckies, as a way to gain info about currents. He calls this study 'flotsametrics'. He also occasionally puts out a Beachcombers' Alert Newsletter.

Staring Hitchhikers
Will hitchhikers get more rides if they stare at oncoming drivers or if they look away? A 1974 study published in the Journal of Applied Social Psychology attempted to answer this question:A field experiment was conducted in which a single male, a single female, or a male-female couple attempted to hitch rides at four different traffic locations, under conditions in which the hitchhikers either stared at or looked away from oncoming drivers...
In the stare conditions, E stared at the driver of the target vehicle and attempted to fixate on the driver's gaze and maintain this gaze as long as possible until the driver either stopped his vehicle or drove on. In the comparison conditions, E looked anywhere else but at the driver. Thus, on some trials E looked in the general direction of the car; on other trials E looked at his feet, the road, the sky, etc. Es were specifically instructed to neither smile nor frown, and to maintain a casual (neither rigid nor slouching) body postural orientation while soliciting rides.

The two hitchhikers were described as, "both 20 years of age and both dressed in bluejeans and dark coats. The male had short, curly blond hair, and the female, straight, shoulder length blond hair. Both could be described as neat, collegiate, attractive in physical appearance, and of an appropriate age to be hitchhiking."

(not one of the hitchhikers in the study)
Staring is often interpreted as a threat. So the researchers anticipated that staring at oncoming drivers might result in fewer rides. But the opposite turned out to be true. Which is a useful tip to know if you ever need to hitchhike. But what really helped get a lot of rides was being a single female. From the study:
it seems that the effect of attempted eye contact and sex of hitchhikers were such that a staring female got the most rides and a nonstaring male the least, with a staring male and a nonstaring female in between.
Contrary to popular belief and hitchhiking folklore , it was no easier for a male-female couple to hitch a ride than a single male, and a mixed sex couple was less successful at soliciting rides than a single female hitchhiker. Although the generality of this conclusion is limited by the fact that it is based upon results obtained by one male and one female E, it is probably the case that couples are less successful hitching rides because of space limitations in the cars they approach. That is, it is more likely that the driver will have room for one additional passenger than that he will have room for two or more additional passengers in his car.

Incidentally, the experimenters never actually ever got in a car with anyone: "After a motorist stopped to pick up one of the hitchhikers, he was politely thanked and given a printed description of the nature of the experiment. No driver expressed any discomfort when he learned that the hitchhiker did not actually want a ride."
