This is a picture of a hologram of a water balloon popping.
I got the timing right by measuring the resistance between the needle and my hand (holding the balloon) with an opamp. When the rubber got out of the way the resistance dropped. You can see the wire below my hand.
The gaps on the bottom of the ball of water are from my fingers, and there is a huge spray of droplets in mid-air, right before they hit the plate.
There is a large bucket out of the shot...

Making them is a bit of a long story... The short version is I take a laser beam, broaden it to about a foot in diameter, then split it into two beams. I shine one directly on a piece of film while the second beam shines on an object so the reflected light then hits the film. Where the two beams overlap, they interfere with each other, and the film records the interference pattern (it looks a bit like a microscopic fingerprint). When you process the film, and then shine a single beam on the film, it reflects light which reproduces the other beam.
I'd love to make you one, but be prepared for sticker shock... The film is a bit on the exotic side, I have to order it from a guy in France named Yves Gentet (He does some amazing work). For an 8x10, just the materials cost about $100.
