Good day to all. In this article, the master Alexander will show how to make such a wave pendulum.
To begin with, the author will make a frame out of not a large wooden beam.
Having cut off six blanks of equal length, the edges of these blanks should be cut at an angle of 45 degrees.
Then he cut off three more blanks, but the edges of these blanks were cut at right angles.
Then he assembled two triangles from the first six blanks.
Having missed the joints with glue.
And fixed with brackets.
It turned out two such frames.
Since the best effect of the finished pendulum will be visible in the dark, the author will cover the tree with a dark stain so that the light tree does not draw attention to itself.
While the tree dries, the author will make loads of 12 ping-pong balls. Wrap one half of the ball with electrical tape and cut in half.
After, the second half of the ball, he also covered with electrical tape.
Then, gypsum was poured into the container.
And poured water.
After mixing everything well, until smooth. The consistency should be like sour cream.
Then he filled balls with this mass, placing a piece of fishing line in each ball and left them until the gypsum completely hardened.
After the gypsum has completely dried, removed the electrical tape.
Such pendulums turned out.
Then the author fastened both frames together, with three blanks with straight slices.
Further, the author pulled the thread in the middle of the finished frame, at an angle.
And hung all the balls on the level of the stretched thread.
Like this.
After painted the balls with fluorescent paint.
And left until the paint has completely dried.
Here is the finished wave pendulum.
Test. The operation of the pendulum in normal daylight.
Test. The operation of the wave pendulum when illuminated by an ultraviolet lamp. The same effect that the author mentioned earlier.
That's all. Thank you all and see you soon!
