I want to ask one question which is based on image but I don't know how to insert image while typing question I'm typing on my cellphone.

You have to find the URL of the image you want, eg: http://www.somewebsite.com/image_name.jpg and put it between img tags, like this:

Code: Select all

[img]http://www.somewebsite.com/image_name.jpg[/img]

Note the end of the URL must end in .jpg, .gif, or .png

Is it possible to create spiral by this way ? Is the image is original or edited one?

Looks real and possible to me, though I suppose it wouldn't be impossible to fake, either.

First thing is that these droplets lines are not emanating in equatorial plane of ball.and the second strange thing is illumination angle of ball is different than the hand.is it?

First thing is that these droplets lines are not emanating in equatorial plane of ball.

Sure it is.

(How can you tell in a still frame where the equatorial plane of the spinning ball is?)

and the second strange thing is illumination angle of ball is different than the hand.is it?

The transparent droplets are back-lit by the Sun.

It should be same as the plane of spiral.

[Gawade Bhikaji]

watch neatly, it seems that ball is placed over the plane of spiral and not that the equator of ball is coplaner with the spiral.

[geckzilla]

There's a shadow cast by the ball which sort of obscures the plane of the spiral nearest to us and the ball.
