How To 1 : Guaranteed Splash!!!

Did you say guaranteed splash with MJKZZ WDK? Yes! This actually works for any other equipments, as long as it has a digital reading.

 

This tutorial is actually an addition to user manual for my upcoming super controller with 6 channels and 16 different sizes and delays for EACH channel. Along with a precision valve. However, this method should work well with current WDK equipments, too.

 

The method described here is very generic and independent of thickness of water solution, independent of water pressure, independent of height of setup . . .

 

Without further ado, here is how:

 

Step 1 -- Finding exact momnent when a drop hits water surface. -- adjust FD and take pictures so that the drop is just about to hit water surface (shown as 1 in above picture). Fine tune it until you get 3 in the picture where the drop is half way in the water surface. Record the FD, in above picture case, the FD is 345. For your setup, it could be (most likely so) different.

 

2. Adjust FD until you get tallest worthington jet like the 4th one in above picture. Record the FD reading, in above picture, it is 485.

 

3. Set number of drops to 2. Set the size of second drop to be moderate, in above picture, it is 60, same as the first one.

 

4. Calculate delay between 1st and 2nd drops: 485(peak) - 345 (reaching surface) - 60 (size of second drop) = delay needed between 1st and 2nd drops, which in this case 80. What does it mean? It means if the second drop can reach the water surface while the first one is peaking, there must be a collision (unless the worthington jet is too thin and not going straight up)

 

After setting D1=80 (delay between 1st drop and 2nd drop) I got collision splash like those shown as 5 and 6 in above picture.

 

This is very repeatable, though less interesting than those by pro dropper, nonetheless, it is a start.
