Robert Tiso still enchants by creating water music

Robert Tiso, a master musician who plays classical music on water glasses, has released several new videos of his music, which is nothing less than mesmerizing.

I first encountered Robert six years ago and featured his “glass harp” in Water Ways Nov. 9, 2009, after corresponding with him by email. His biography is fairly well outlined in that blog post. I believe he was in Italy at the time.

It is worth mentioning again that Robert performed in a DVD documentary “Bach and Friends” by filmaker Michael Lawrence. View the Robert Tiso performance on the film’s trailer.

At the beginning of last year, Tiso moved to the United States, where he performed in Las Vegas as part of an eclectic production called “Vegas Nocturne.” The production was featured at Rose.Rabbit.Lie, a venue at the Cosmopolitan hotel and casino. He has since returned to Toscana, Italy, but still performs all over the world.

New videos released this year include:

The first two of these videos can be found on this page. The Water Adagio is from Bach’s violin concerto 2 in E Major. The first phase of the piece was used in a movie by Pierpaolo Pasolini for scenes in which Jesus Chris performed miracles, according to notes on the YouTube page. In this performance, the tone oscillations are created by tilting the table to make water move inside the glasses.

A whole series of videos by Robert Tiso can be found on his YouTube Channel, including an intriguing duet with Felice Pantone, who plays the mysterious musical saw. I remain as intrigued by Robert’s music as when I first heard it.

Later, I learned that Benjamin Franklin loved the sound created by crystalline glass. As an inventor, Franklin believed it was a waste of time to fill and tune each water glass when they could be made to play just as beautifully without water, provided they were made to the proper size. Read about his amazing invention in Water Ways from June 3, 2013.

Amusing Monday: Surprises from a drop of water

I find myself returning again and again to videos that surprise me with scientific phenomena, such as a droplet of water bouncing at least three times before it gets absorbed into a glass of water.

Using videos to reveal something visually exciting is a thousand times more rewarding than watching a science teacher explain the properties of matter. I wish that teachers would have had some amazing videos available when I was growing up. But considering today’s technology, maybe teachers find it more challenging to surprise their students.

Anyway, check out the first video on this page, which shows a couple of goofy guys fascinated with the idea that water can bounce. The value of this video lies in the fact that these two “Slo Mo Guys,” Gavin Free and Daniel Gruchy, seem to be having a good time exploring this feat of nature.

That first video is fun and all, but is it enough? If you’re like me, you want a little more. You know that this relates to the surface tension of water, something the goofy guys never seem to mention. So I found another video, which has even better photography — plus a mathematician able to explain what’s going on. Check out the second video by Molecular Frontiers, a nonprofit group of scientists dedicated to spreading an appreciation of science. Maybe they’re a bit more professional than the Slo Mo Guys.

If you would like to delve further into the surface tension of water, I recommend a couple articles in Wikipedia, one on surface tension and the other on hydrophobic properties.

Finally, getting farther afield from where I started, a company called Ultratech has created two amazing videos about its super-hydrophobic product called Ultra-Ever Dry. It shows how treated products cannot get wet or dirty. See Ultra-Ever Dry 1, Nov. 12, 2012, and Ultra-Ever Dry 2, Jan. 31, 2014.

Ultra-Ever Dry is a product based on nanotechnology, and the formulation is mostly proprietary. As amazing and useful as nanotech products can be, I should point out that some concerns have been raised about potential long-term effects on the environment if they were to come into common use.

The Slo Mo guys, featured in the opening video, have also played around with a super-hydrophobic surface, as well as tiny particles of metal in a liquid. Believe it or not, they were invited into General Electric’s Global Research Lab in New York, where they felt free enough to bring along their playfulness for a video they made there.

These two guys also got invited to use a more advanced camera to watch what happens when they shoot a gun underwater. In the video of the bullet launch, the prime segments come between 2:20 and 3:30 and between 5:25 and 6:32.

If you want to see more of the Slo Mo Guys, check out the video of them bouncing on a giant water balloon — or visit their YouTube Channel.
