Air Pressure Droplets

This time I try to make some different with the droplets.
The first drop come from below. I use a little container filled with water and about 1 bar pressure. Through the solenoid valve, controlled with the Camera Axe trigger, I shoot water to the top, then a couple milliseconds later the second drop fall from above and collides with the first one.
Of course also this time I use food color for the water and different filter for the flash.

 

 

Drop collisions (drop-on-drop)

One drop falls down into water and bounces back up. A couple milliseconds later the next drops comes down and collides with the first one. Photos taken with help of the selfmade microcontroller CameraAxe to trigger the flashes.

Moments you can not see with your eye ...

Some moments you can not see with your eyes because this moment is to fast, like milliseconds.

With this picture I can show you this moment.
One drop fall down inside some fluid, in my case I use just normal milk as the drop and coffee where the drop fall inside.
The first drop of milk fall in the coffee, after he hit the surface of the coffee he build a crown, then the crown change into a crater and the drop build a pillar what comes out the coffee. Now after this procedure I let fall the seconds drop of milk. The second drop will fall after 40-60 milliseconds, then he hit the top of the pillar and build a little shield what you can see at the picture.
Again after a couple milliseconds I make the picture.
Because this moment is pretty fast I can not use the shutter of the camera, to slow.

I make the picture in a quite dark room, open the shutter in the bulb mode, let fall the first and the second drop and after 200 milliseconds from the beginning I trigger the flash. The flash should flash very short, with the Speedlite 430 I use 1/64, this should be about 1/20'000 to 1/25'000 of a second.
If I change the delay for 1 millisecond you can see on the picture how the drop on drop change the appearance.

Central Plaza

This is one of my favorite place's in Bangkok. A couple year's ago I was so happy to hear that they will build one also in Chaeng Wattana Road. This is pretty close to my place here where I live if I'm in Bangkok, only 10 minutes to walk.

Anyway this time I go there just to see what is new since a was there last time. I think it is in the 6th floor, there are 4  fish tank's with many many little fish's inside. I don't know the name and also I don't know what they will do and i never see before. The woman told me to put my hand inside the water and then the little fish will come and eat the skin scales. I really need a couple minute's to think about if I will do or not, because I could image that it will tickle so much. First I put my finger inside the water, so fast the fish come and start to eat some from my finger. I thought I can stand take off my shoes and put my foot inside the water.

Wow, as soon as I put my foot inside the water, I don't count how many, but so so many little fish come and start to eat the scales from my foot and it tickle so much. If you want you can count ...

First I must really laugh so loud that some people who walk there look at me. I wonder what the thought :-)

 

At the end I could stand to leave my hand's and my foot's for 30 minutes inside the water.

Now I know that the name of the fish is Garra Rufa, also named as Doctor fish.
