Speaking of methodology, the water balloons them selves are going to cause a lot of variation in measurement. For starters, the exact dimensions of the balloons (how full they are) will change how much water the bullet has to push out of the way (how much speed and energy it loses) to traverse the balloon. Where exactly the projectile strikes on the balloon is going to have a similar bearing on the results - if the bullet hits center-mass on the balloon it has to push all of the surrounding water outward, where a bullet near the edge will have to push significantly less (the water between its path and the edge of the balloon), not to mention its straight path through the balloon will be shorter. In the near-edge case, the difference in work needed between the center-mass side (more water to push against) and the edge-side (less water to push against) of the bullet will result in the bullet's path curving away from the center-mass. The balloon will pop, but the bullet may miss the next balloon in line, and the energy lost passing through the balloon will differ greatly. For instance, the crossbow bolt goes through the necks of the balloons (much less water there than center-mass), and misses one entirely. Real science is slow, tedious and requires attention to details like this. It's boring, but that's how you get real, consistent results. The original video was pretty much a carnival gimmick... Fine for a guess-how-many-balloons video, but there's not much point in taking it beyond that without reworking the whole shebang.
Methodology is important in all tests, but unfortunately I can't explain all the details in the video because it makes it longer and as you say, it's boring. We had a timer for each balloon as it filled with water. However, there are strong variations in the thickness of the rubber of each balloon so each one would hang at different heights. We set up the balloons so the first one wasn't hanging as low as the next. That way as the bullet drops, the balloons did too. The crossbow bolt was aluminum, and after several shots we used the best one. The mass of moving water was no match for lightweight aluminum. It's not a lab setup and I'd like a few things different, but it was fun. That was important to us. I'd prefer more scientific control of the variables. Maybe this year I'll do it again with different materials. Thanks for your comments.
Hopefully, no one. Understanding how guns work along with a little knowledge of gun safety, it shouldn't ever happen. The gun wasn't loaded, and it's a single- and double-action revolver. It would be near impossible to create enough pressure to move the trigger while spinning a revolver in single action mode. Lastly, fingers rest against the trigger guard while twirling the gun, not the trigger.
Great video! The only thing I would suggest is having the balloon pop counter and caliber in each shot after the first. It disappeared kinda quick. Also, who's that awesome guy with the sparkle in his teeth?
Hi Georgij, because water is so dense, it quickly slows the bullet's speed. If we fired the guns lower, many bullets would have left the path of the balloons, falling below them.
Hello, I'm writing from October Films, an award winning television production company based in London. We produce a range of exciting and innovative factual based programming for broadcasters globally, you can find out more at www.octoberfilms.co.uk. We are currently making the 5th series of a science television show for Discovery called ‘Outrageous Acts of Science’ in the U.S. (known as ‘You Have Been Warned’ in the UK). The series features the best web clips from around the world and explains the fascinating physics, maths, chemistry or biology that made them possible. You can find out more information and have a look at clips from previous episodes here: www.sciencechannel.com/tv-shows/outrageous-acts-of-science We have come across this amazing clip in our research and would be interested to include it in the programme: How Many Water Balloons Stop a Bullet? Do you own this clip and if so, would it be possible for us to use it? If you are not the owner of the above mentioned clip, I would be just as grateful if you could confirm that this is the case and, if possible, give me any indication of who is the rightful owner? Please email graham.evans@octoberfilms.co.uk So we can discuss further Best wishes, Graham

3:26 I know what you're thinking, "did he hit six balloons or only five?" Well to tell you the truth in all this excitement I kinda lost track myself.

I wonder how many people have shot themselves or someone else on accident twirling a gun

Water bullet
Curious what would it look like with just balloons of air?
ua-cam.com/video/j1CnTEbMllU/v-deo.html here you go buddy
You should shot lower, coz it's shorter distance bullet must go though the water in the top of the baloon ...
