The sand timer hourglass is sometimes referred to as a sand clock or a sandglass. Like other timepieces, it needs to be carefully calibrated. The hourglass maker must test the instrument and fine tune it to measure the correct length of time.
There are many factors that contribute to the ability of an hourglass to accurately measure time. The type and quality of sand is key. It must have a rate of flow that does not fluctuate. Sand that is too coarse will wear away the glass, eventually making the neck too large. Most important is the ratio of the neck (the hole, or tube) width to the diameter of the sand particles.
Here are the other factors that affect the accuracy of an hourglass:
The amount or volume of sand used
The size and angle of the glass bulbs
The quality of the sand or granular material. It must be fine, dry and consistently formed so it can flow smoothly. (Some substances used in the past were fine grain sand, powdered eggshells, and powdered marble.)
The width of the neck
A tight seal so no moisture can get into the chambers. Moisture can add weight to the sand or clog up the neck.
A flat and level surface on which to rest the hourglass
Like a foam roller, a massage ball can also be used to help release tension in our achy muscles after long hours spent in the office or after a workout. One of the differences being that it can get to those hard to reach areas such as the upper back, buttocks and feet. “Knots” or “trigger points” can be massive sources of pain in our bodies and using self-massage techniques can be very satisfying. Before diving in, there are a few important things to know which will help you achieve the best results.
Why a massage ball
Massage balls are affordable and small and therefore they can easily fit into a suitcase or handbag to use wherever you go. They also promote self-sufficiency so there is no need to rely on anyone else. Notwithstanding, it does not always give the same results as a traditional massage delivered by an experienced therapist
Find the right ball
There are many different types of massage balls ranging from very smooth and firm like a lacrosse ball to small and soft like a squash ball. Other balls include a tennis ball and the trusty spikey massage ball. To each his own but if you’re new to using a massage ball, perhaps start with a spikey ball or a tennis ball.
History
The mid-to-late 1800s were sentimental and romantic times, heralded by an emerging middle class, resulting from the matured Industrial Revolution. Letter writing became a fad, and paperweights were sold in stationery stores as an attractive accessory to desk-sets of pens, inkwells, blotters, and fine stationery. The first glass paperweight was made in 1845 by Venetian glassmakers in response to the letter-writing fad. They could have been made 300 years earlier because the techniques were known, but paper was then a rare commodity and there was no need for a paperweight. They are the perfect example of form following function.

HIKINO was conceived in 1962 by the late Dr. William McLean and engineered by D.K. Moore of NOTS, China Lake. The two-person vehicle had the shape of a catamaran with the acrylic sphere suspended between the two hulls. The acrylic sphere itself was assembled from two free-formed hemispheres mated at the equator to a metallic joint ring.
