I saw this on the TV show "Time Warp" and thought that I could do that. Well it turns out that Noah and I could do it! I was a little surprised at how small the parameter space was to achieve a good series of bounces. Near the end of this clilp, you can see waves entering from the lower right. I think these are reflections of a low frequency sloshing modes set up by the initial droplet. The smallest droplet bounces off these waves and start moving off to the side. In any case it is pretty cool. The only issue is that there was some dust on the sensor (dark spots that don't move). The camera is a Vision Research Phantom v7.3 high speed video camera.

  • I love that many people think that this is somehow a simulation, when in fact it is absolutely real. There is nothing here other than a syringe, water, and a high speed camera.

  • A friend's research group in Material Science bought the camera to study high speed collisions. His task was to learn how to use the camera, so we decided to have some fun on Saturday.

  • I am not certain how much the camera is, but I think it is around 10k$.

  • thats fascinating

  • @headlesskiller

    No. Eventually the drop is too small to escape water tension.

  • Makes me wonder, does it continue to get smaller, too small for even this camera to see?

  • a drop within a drop within a drop....Dropception!

  • @porkyminch01 just jokes, didnt mean any offense

  • @ToMichaelJackson im joking guys, its obviously real (and extremely interesting at that), i was just in a bit of a trolly mood was all, and i fear i may have been a tad successful

  • @TheClumsyGoalie judging by your battlefield 3 videos you are one of those that thinks everything is made in computers, well this is not the chase at all you gentooman.

  • @TheClumsyGoalie Stupid and ignorant.

  • fake and gay

  • cohesion!
