Today we take a look at another water splash caused by compressed air.
Materials
Water, pan, air can.
Observations
I think this one may be my favorite of this series. I especially like the big vapor bubble that forms in the back, camera left. The globules of water floating through air look neat too. The pattern of the splash is so unlike a normal splash in these instances.
Today we have another shot of a light bulb burning itself out and the smoke exiting from a small hole.
Materials
60watt Black light bulb.
Procedure
Create a hole in the bulb. I used a dremel tool to take care of that.
Result
The filament heats up and then proceeds to produce a thick (pleasant looking) smoke before burning out.
Observations
I like this one because you get to see the smoke contained by a barrier, while at the same time you get to see a limited amount escape and curl around the barrier. The smoke is also rather pretty in and of itself.
Additional notes
If it looks like I’m scraping the bottom of the barrel for my clips, it would be because I am. I am currently in-between cameras so I’m searching through things I’ve not posted in the past because I had better clips to post. Hopefully this situation will change in the near future.
This is another shot of Matt Deal (of Matt Deal Farms fame) jumping off of a deck into a pond.
Materials
A dock and a pond.
Procedure
Instruct a man to jump off a dock. It is quite amazing what one can get people to do if one has a camera. People seem to feel quite natural and somewhat fearless in front a camera. I can’t explain it, though it would be interesting to listen to someone who can. Perhaps one of our readers is a psychologist and can illuminate this for us.
Observations
This shot is another great look at the muscles of a well toned person. The subject in question has over years of farming toned his body up quite completely. Makes for an excellent video subject for a study in bio-mechanics. I plan on subject Matt to many more indignities over the years for your viewing pleasure. Next time I think I’ll make him take a few swings with a bat at a small, round moving object. Again, the splash is wonderful as usual. The light catches it all nicely. Poor Matt in this shot was unaware that the pond was only a few feet deep, much to his surprise. Sadly I don’t have enough disk space to export the entire clip (yes I filled up yet another hard drive, over 1TB of data now!) but I still have the original so when my new drive shows up I’ll re-export this shot and do a close up on his rather surprised face. It is quite amusing.
Today we take a closer look at a video we posted a while ago. In this video we have pushed in to put you right at the center of the explosion. There is enough detail to actually watch the vectors of the fluid movement.
Materials
We can skip this, if you don’t know how to make this already, you don’t need to be making it.
Procedure
Detonate using electronic detonation.
Result
This is a crop of the previous video found here. This puts you right in the center of the raging fireball. You can see the movement of the fireball fairly clearly in this video. It is interesting to note how the flames move and evolve. At speeds like this you really get a chance to see things that are ordinarily invisible to the eye, the motion and formation of the fireball being one of those things.
Today we take a look at a printer my daughter tossed off of a concrete wall.
Materials
A dead printer, copier, scanner thingy.
Procedure
If you have a youngin’ you can skip the following steps….actually we’ll skip those steps entirely as I don’t feel up to writing a biology lesson. Have your youngin’ climb up to the top of the concrete wall, pass up the printer and give them the command they’ve been waiting for their entire lives. “Go ahead, toss that printer off the wall!”
Result
In short, a mess. It is interesting to see how the printer obliterates itself. If anyone had any doubts about the validity of gravity I hope this video puts their mind at ease that it is indeed still functioning to spec. The glass was obviously broken in previous attempts, as were parts of the printer, which made this one such an interesting shot. This was the third time we had dropped it. I have to say that Epson makes very sturdy printer, the first time we dropped it not a single thing broke. An eight foot fall and nothing broke. Amazing for a heavy, plastic printer like that. Anyway, enjoy the destruction.
Today we look at a large lightbulb being rather unceremoniously smashed against a wall.
Materials
A large dead light bulb.
Procedure
First determine your distance from the wall, A. The force at which you know you can throw, B. Then take the circumference of the earth minus A, and throw that away, it is quite useless. Then take B and go ahead and chunk that too, you won’t be needing it here. Then figure in the wind speed and gravity (9.8m/s/s in most places, your gravity may be different, please inquire at your local post office). Take all of these things and write them down on a large brown piece of paper. You won’t be needing them again. Now toss the bulb at the wall.
Result
A rather large and somewhat unsafe explosion of lots of tiny pieces of glass that can get lodged in your eye if you don’t have safety glasses on. If you do have safety glasses on, congrats you are now safely protected on a very very small portion of your body. In all seriousness this is a neat shot that I rather enjoy, one piece of glass becoming many. Mechanical reproduction at its…um….finest.
Today we have yet another death of a water balloon. In this particular situation, the balloon was in a gold fish bowl.
Materials
A goldfish bowl.
A water balloon, blue.
Observation
This is an interesting shot. Primarily because the water is contained and cannot escape in the normal manner by which water likes to escape. The water, not being aware that it was trapped in a goldfish bowl, still tries to escape to no avail. Having failed to notice that it failed to escape the water continues about its business of playing with gravity in a not entirely unpleasing manner. The bubbles are neat too.
