I do high-speed science experiments to measure the change in time and energy during everyday processes.
Steel Bearing into Ham
A pnuematic gas accelerator was used to speed up a 1 inch steel bearing to ~ 100 m/s into a ham. This experiment was done with Mike Rose, a high school physics teacher. Enjoy!
Video was captured with a phantom TMX color at 1 MPx and 76000 fps.

Life Saver Candy Crush
Переглядів 9963 місяці тому
This is a high speed video of a Life Saver getting hammered by a high-school student studying triboluminescence. This was recorded at 110 000 frames per second, with 7 microsecond exposure, and a 100 mm Zeiss lens. No luminescence was observed due to the fact that the number of scattered photons dramatically outnumbered the number of emitted blue photons. The key to view the emission is to open...
Triboluminescence of Life Saver Candy
Переглядів 1 тис.3 місяці тому
Triboluminescence, simply put, is the emission of light when a material is mechanically broken. We are generally unfamiliar with this process because when it happens, it occurs extremely fast. A popular example, shown in the video below, is when a Life Saver candy is chewed, ground, or hammered. The fracturing of the candy emits blue light, but despite the clear characterization, this phenomeno...
Water hitting Frother
Переглядів 1,4 тис.5 місяців тому
A milk frother was sped up to around 215 revolutions per second, and water was poured directly from the top. Really neat dynamics. Enjoy This recording was done with a VEO710 at 1280x400 at 14 kfps and 7 us exposure time. Used a 100 mm Zeiss Makro closed down to ~f/5.6. A pair of GS vitec QT LED were used to back and front light the scene.
Horse Gait Motion Analysis
Переглядів 6975 місяців тому
In the period from 1872-1880, Eadweard Muybridge 'recorded' arguably the first ever high-speed 'video'. Records show that it all started with a bet initiated by a gentleman named Leland Stanford who hired Muybridge to prove that all four hooves of a horse are off the ground at the same instant during a trot and gallop. At that time, they captured pictures by exposing a viscous silver nitrate so...
Interfacial Water Boiling
Переглядів 9995 місяців тому
A group of researchers were interested in understanding how water boiled when heated within a very thin glass chamber. I created a ~ 1 inch by ~ 1 inch cuvette with 1 mm thick chamber by super-gluing glass slides together, and then used tap water and hot plate to investigate the boiling process. You can see nicely the formation and destruction of vapor bubbles. The record speed of this video wa...
Shockwave from Explosion
Переглядів 1,9 тис.Рік тому
"In physics, a shock wave, or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and density of the medium." - Wiki 2-27-2023 In this video, a m1000 is exploded and ...
Glass Crack Rate
Переглядів 2,1 тис.Рік тому
Materials science text books say that many glass cracks at speeds like 5 km/s. That means if you have a 5 km-long piece of glass (that is 3.1 miles), and you create a fracture down the middle of that glass, it will take only 1 second to reach the other side. That is 15x faster than the speed of sound in air. As for mechanism, the American Ceramic Society states, "A wave moves in one of three wa...
Bullet Impacts Crayons
Переглядів 2,2 тис.Рік тому
How much energy is transferred from a bullet to a crayon during an impact? Does it pass with insignificant energy/speed loss? How many crayons should it take to completely stop a bullet? Very difficult to guess without some testing... A fun way to go about this is to fire a bullet through a series of crayons and determine the speed delta from before and after impact. Then, you could approximate...
Underwater Balloon Pop
Переглядів 3,9 тис.Рік тому
An air-fill balloon is anchored to the bottom of a water-fill tank. A syringe is shot down at the balloon to induce a rupture and popping of the balloon. The physics of the balloon collapse is quite different than when the same balloon is popped in air. v2640 8500 fps 70 us
Ball Impacts Biomimetic Jelly
Переглядів 2,2 тис.Рік тому
This is a basic example of a partial transfer of kinetic energy from a ball, to energy transfer into the biomimetic gelatin. The analysis at the end of the video is called Digital Image Correlation, which is a full-field strain measurement, which uses the speckles on the surface of the gelatin to determine how the surface is deforming and/or straining.
Cavitation Bubbles
Переглядів 8 тис.Рік тому
The formation and collapse of cavitation bubbles is an intensely studied subject in academia and beyond. In particular, in recent years, researchers have investigated cavitation during blending, underwater propelling, cleaning, focused-lasing, medical uses, and many others. In this test, a small glass bottle was impacted from the top with a rubber mallet. In some cases, if the impact is hard en...

So what you're telling me is flies can't react fast enough to dodge arrows.
Then why them mfs fly away the millisecond I grab the fly swatter from the other side of the house? 🧐🧐🧐🧐
Hi! My company has an offer for you. How can we contact you?
I feel like this video is a good one for the ol “I’ve watched too much UA-cam today” saying.
How did you get the fly to stand on the orange.. did you just wait hours for it to fly on?
It is amazing that those flimsy wings can carry that heavy body vertically.
Fly survived. Orange died.
Maybe if it seen it coming its reaction time would be better smh
The fly is already dead, but still it is flying
If you move really slow, u can actually crush them without flying away. Outdoors it's easier then indoors. Because there's less wind inside.
Can fly away in 8ms, can't see slow moving things.
The trick to swatting flies is not to swat where they are, but to clap your hands about 1.5” above them. Middle East has flies everywhere and I would go 8/10 on a bad day.
Who hurt my pookie fly
Strange to see a fly flapping its wings like something majestic
Next time hit aim at the fly
Did you use the same fly?
Did you know that if you move your hand really slow to a fly, it doesn't actually notice how close you are?
i like how he retracts his landing gear when setting off to fly
The fly has a considerable amount of lag
When we were watching porn magazines in a childhood, our reaction time were the same
Now I know.

I will teach CS to my pet fly
bro got 8 ping
Man would be the ultimate cs player
sivrisinek 1 milisaniyede tepki verir... inan bana :=))))
bro shoot an arrow going mach 10
Ping of 8ms is crazy
You guys should be more careful with your tests, that arrow barely missed the fly.
Noted
Best footage of this I have seen
I invite you to read Quran ❤
Dont waste food
no ciekawo ciekawo
For no reason at all, replayed it 5 times before i realized the whole video would've replayed it in slowwer-mo
i thought this is a meme video
They wanted to hit the fly, failed miserably and made this video instead as an excuse...pathetic
Known as impulse I=F[tf-ti]
Blud has better ping than me
So this is why I struggle to swat them
Now conduct this thousand times and take average for appropriate reading
Só de comparação, o tempo de resposta médio de um humano é de 200ms
Jeez, Bud took 4 business days to react.
Slower than nate diaz
I dont care about your channel but youtube keeps showing it to me and i dont want to see it. I am the downvote
Who pissed in ur cereal?
@@Jris-qv7wb The algorithm
The moment I knew I was the chosen one was when I caught a fly mid air at 12 years of age.
so a cat can catch it or not?
Ahh the great wave...
Excellent! Now do with a fly sitting on a big pile of steamy horse dung.👍😉
The crazy thing is they are suspended in air the whole time. Their flight response timing is just fast enough that they don't even get to fall at all, I wonder if that's by design.
This is the most hardcore way you could possibly test this, it's so fricking funny, I lost it when I realized an arrow was piercing through the citron 🤣🤣🤣
