Day 21 - Hula Hoop


Changing over to dropping liquid into a basin with a black background is more complicated than I expected.  Flashes need to be moved to the front and side, and liquids have to be made opaque or else they will not show up against the black background.  The same was true for the crowns earlier this month, but they were being dropped onto a piece of plexiglass, and here, the water must be illuminated at least a little.  The drops were made opaque white using a bit of cream, but the basin water remained clear, but with food coloring.   The white drops fall into the basin and the ensuing jet/column that rises brings with it some of the basin water and some of the drop water, so you see a mix of the two colors, and luckily some streaks of the basin water show through.  Timing is also altered since the liquids are thicker and behave differently than without the cream.   Because of the added thickness, it's also harder to get a wide spread on the collisions.  Time to put on my thinking cap to see what I can do to 'grow' the splashes.

I like how the hula hoop is formed by the start of the disintegration of the 'plate' that formed when the drop collided with the column.  Just a hint of daylight shows through around the column.  And don't you know that hula hoopers now require safety helmets!

  1. Oh by far I love the black backgrounds the most. This is a gorgeous blue and a wonderfully clean collision in your masterful style :)

  2. The blue is so nice with the white against that pure black background. Love how the column looks illuminated from inside.

  3. That is a lot of science involved to get what you want.
    I'm the lucky one that gets to sit back and enjoy ;) all those shades of blue.
