Phase Locking Folk Toy 20
A post shared by physicsfun on Jul 6, 2020 at 10:44am PDT
This plastic version of the toy is from the 1990s and I’m not sure of its orgin. However, it is not hard to construct these toys.
A detailed physics analysis of this toy was publisehd in 2018 : Physics of the mechanical toy Gee-Haw Whammy Diddle
Versions of the regular Gee Haw Whimmy Diddle available from these sources:

Phase Locking Folk Toy 2.0: this version of the hooey stick toy has two rotors- and often they will rotate in opposite directions! Just as with the regular version of this toy rubbing the stick over the notches creates vibrations- and can lead to an up and down motion of the shaft in the center of the rotors. The hole in each rotor is larger than the shaft, and when the shaft/notched stick is vibrating it only touches the rotor for a short time each cycle- if the timing is right the stick collides with the rotor such that friction gives it nudge with each vibration to set it spinning- and this can work either clockwise or counterclockwise. Sometimes they spin the same direction and sometimes opposite, which seems to depend on initial conditions and a bit of luck.

The silver proof versions can be expansive, but sometimes the circulated coins are available at a lower price.
Click to see more: shapes of constant width
Coins of Constant Width: the only coins produced in the shape of the Reuleaux triangle, issued in 1997 and 1998 by Bermuda. The special convex shape of the Reuleaux triangle will roll, because like a circle they have the same diameter from one side to the other, no matter their orientation. To demonstrate this property note here how two straightedge rulers remain parallel as the coins rotate between them, just as one would expect circles to behave! Bermuda triangle coins were only produced for two years and featured Elizabeth II on the front and shipwrecks on the back- this one depicts the wreck of the Sea Venture.

Sphere and other Orbiforms: pi day special post- volumes of constant width made from solid brass. These shapes have constant diameter no matter their orientation and will roll like spheres between two planes- note how the acrylic plate stays parallel to the table as the sphere and other orbiforms roll underneath. The first orbiform is based on the Reuleaux triangle and the second on a Reuleaux pentagon. Fun pi fact- the perimeter of any shape of constant width is alway equal to the diameter multiplied by pi: P=d.

Who Is Curiosity Box For
From exploring our first Curiosity Box with my nine-year-old son, I feel this is for older kids and adults. If youre looking for an age range, Id say 10+. Officially, it is for everyone 13+. Younger kids will still enjoy some of the activities, but they might not really get what they are doing.
My six-year-old daughter thought the science experiments were fun but didnt fully grasp some ideas like the solar can .
Thats not to say that younger kids wont find Curiosity Box interesting. Some of the science toys included were fun for everyone. My son especially liked showing off one of the puzzles to his younger sister.
If your kids are on the young side and you want to check out some of their science and puzzle toys sold separately, you can find all of them here.

Water Drop Pulse Kinetic Sculpture
Art by Philippe Bouveret available here:From the artist: BUY NOW philippebouveret.com
Water Drop Pulse Kinetic Sculpture: Heart In A Bottle is a kinetic art sculpture by Philippe Bouveret that utilizes the amazingly strong surface tension and adhesive properties of water. Two halves of a heart are attached to a wire spring which is periodically pulled together in a zipper like fashion by a single drop of water . The engineered system in the top bulb emits a water drop that adheres to the two wires, and as it falls surface tension pulls and connects the spring wires, which stay stuck together until gravity pulls down and thins the water coating enough such that the spring force can overcome the waters adhesion. The halves of the heart then undergo vibrations that damp out until another drop forms in a process that repeats a few times a minute.

The classic drinking bird heat engine can be found here:From Educational Innovations: BUY NOW Drinking Bird Engine
Drinking Bird Heat Engine: this classic physics toy came in my The Curiosity Box which provided this orange species of the bird complete with dapper top hat emblazoned with the Vsauce logo. Cooling by evaporation at the head leads to lower pressure in the top bulb, the pressure in the bottom bulb pushes the dichloromethane fluid up the neck making the bird top heavy and the bird tips over dipping its beak and letting the fluid return to the bottom bulb. The process repeats, and as long as the top stays wet and cooler than the bottom this heat engine will continue to cycle.

When Will Your Box Ship
I wanted to include this section because it was a little confusing at first. Most other educational subscription crates and boxes are monthly, but The Curiosity Box is seasonal. This means there might be a bit of a gap when you receive your packages.
How will shipping work, and when will I get my Curiosity Box?
The newest Curiosity Box will begin shipping within the first week of the following Months: March, June, September, and December.
For example, if you purchase a box in June , your first package will ship right away. Your next package wont ship until August when shipping for that season begins.
This is the same for the seasonal plan and the yearly plan.
For another example, if you order during the winter season, say in January, youll receive the winter box immediately. Then, if you continue for your next order or sign up for the yearly plan, youll receive your spring box in March. So depending on when you order, you could be charged for two boxes in a short amount of time.
