5+ Easy Steps To Create A Homemade Periscope

A periscope is an optical instrument that allows one to see around corners or over obstacles. It consists of a tube with mirrors at each end, one of which is semi-transparent. Light enters the periscope through the objective lens and is reflected by the first mirror to the second mirror, which then reflects it to the eyepiece. The observer looks through the eyepiece and sees an image of the scene in front of the objective lens, as if they were looking directly at it. Periscopes are used in a variety of applications, including military, marine, and industrial settings.

Periscopes have been used for centuries, with the first known example dating back to the 16th century. They have played an important role in military history, allowing soldiers to observe enemy positions without exposing themselves to fire. Periscopes are also used in marine applications, such as submarines and diving bells, to allow the occupants to see above the water’s surface. In industrial settings, periscopes are used to inspect machinery and other objects that are difficult to see directly.

5+ Unconventional Methods to Measure Your Weight Without a Scale

Determining your weight without a scale can be useful in various situations, such as when traveling or when a scale is not readily available. There are several methods you can employ to estimate your weight with reasonable accuracy.

One common method is to use a measuring tape to measure your height and waist circumference. You can then use a formula to estimate your weight based on these measurements. For example, the Devine formula for men is:
Weight (kg) = 56.2 + (1.41 x height (cm)) + (2.09 x waist circumference (cm)) – (0.18 x age (years))
And for women:
Weight (kg) = 43.5 + (1.13 x height (cm)) + (2.86 x waist circumference (cm)) – (0.16 x age (years))
Another method involves using a chair and a sturdy object, such as a backpack or a bag filled with books. Sit on the chair and place the object on your lap. Grip the object with both hands and lift it overhead while standing up. Repeat this process several times and count the number of repetitions you can do before reaching exhaustion. You can then use a table or chart that correlates the number of repetitions to your approximate weight.
These methods provide a reasonable estimation of your weight and can be particularly helpful when a scale is not accessible. However, it’s important to note that they are not as accurate as using a scale and may vary depending on factors such as body composition and fitness level.
