You’ve seen amazing shots of water spouts and milk crowns. You’ve seen shots of bullets piercing glass ornaments, playing cards, and poor, defenseless pieces of fruit. Maybe you’ve even seen that holy grail of shots—a bullet piercing a water spout. But how is it done? How do photographers capture this two-headed mythical beast of high-speed photography? [Maurice] has cracked the code and shared it for all to see.
He uses a Camera Axe to trigger the camera, a device he came up with years ago that’s on its fifth version. His setup uses a 100mm macro lens, a key flash, and two fill flashes that sit behind a diffusing wall of whiteness. All three flashes are connected to a multi-flash board which feeds into Camera Axe. [Maurice] explains how he gets nice, tall water spouts by thickening it with xanthan gum. He adds Jet Dry to reduce the surface tension and some food coloring to keep things interesting.
[Maurice] also runs through his pellet shooting rig, which he made with some polyethylene tubing and an air compressor. He ended up shooting the pellets at 20psi, which sends them traveling at 75 feet per second. They move slowly enough that he can use his own stomach to stop them in the demonstration. Dialing in just the right settings to get the pellet to intersect the spout at the right time took some finagling, and that will hold true for anyone who attempts to recreate this setup. He gives a link to his code files in the video description to get you started. Video is after the break.
Amazing skills displayed here. Also good job on the photos.
this is really wild. nicely done!
Thanks guys! If anyone has any questions about this project or high speed photography in general let me know and I’ll do my best to answer the questions.
Is the pellet tumbling from collision with the water or from the firing apparatus? Very cool photos!
It tumbles even if there is no water droplet so it’s from the firing. I think if you wanted to eliminate tumbling you’d need to use a purpose built pellet gun barrel.
The bullet it tumbling because the firing apparatus is not causing the pellet to rotate. That is what keeps normal bullets from tumbling, typically called rifling of the barrel.
