But dont worry, I have much more planned for this laser! TikTok - tiktok.com/@thebackyardscientistTwitter - twitter.com/ChemicalKevyInstagram - instagram.com/backyardscientistlofficial secret discord discord.gg/DqPbGgqThere were never any planes in danger and I can prove it with science. First of all, we never turned the beam on more than 4 amps (50 watts)because we were having cooling issues and couldn't really monitor it up on the car.. (we tried 6 amps once but it was too bright.) So assuming the beam stayed perfectly collimated, the beam would have an area of 430 square centimeters. If the laser was running at 25% power (4 amps/50 watts) that would be about 110mw/cm2 from the telescope. However, your pupil is only half this size fully open, so a pilot could theoretically receive a 50mw/cm2 exposure. A decent amount, but you have to remember even the smallest plane is traveling 150 miles per hour which would limit total exposure time to only 3ms( time it takes to cross a 9 inch beam). That puts it at the cusp of the maximum exposure limit, which is defined as "about 10% of the dose that has a 50% chance of creating damage under worst-case conditions." Here is the chart im referencing en.wikipedia.org/wiki/Laser_safety#/media/File:IEC60825_MPE_W_s.pngSo even under perfect conditions, this would still be 10x less than the exposure that carries a risk of damage. That's assuming perfect conditions, but in reality it was a hazy night, the laser would not be perfectly collimated, the atmosphere would distort the beam, the windows in the airplane would deflect some of the beam, unless the pilot was staring directly at the beam they would receive a smaller dose, I tried to keep the beam moving when up in the sky, and most planes are moving faster. all of this meaning the pilot would be exposed to a much lower amount of laser energy in the real world than under perfect conditions. even at full power this laser is still within the safety factor of the maximum exposure limit. Plus do you know the odds of hitting a plane with a laser when your trying not to? just pick a random star in the sky and wait for a plane to fly over it.

Can a Person escape a human-sized Glue Trap? TheBackyardScientist 2018-09-05 | Join the science discord! discord.gg/pw5sZ3PTye After struggling with my mega-microwave I decided to have some fun. I got 4 gallons of bulk glue for mouse traps because I was curious if a person could escape from a human-sized glue trap.I never saw anybody try it before so I was curious. At first I thought about getting a few hundred of the regular sized glue traps from the store and stapling them to the plywood but decided the bulk glue would be more economical and cover more surface area. It was not a cool color like the stuff in the store but I don't mind.I had fun, thanks for watching!You can follow me on my instagram, facebook, and twitter also!Instagram: instagram.com/backyardscientistofficialTwitter: twitter.com/ChemicalKevyFacebook: facebook.com/TheBackyardScientistOfficial

What happens when a NERF dart breaks the SPEED OF SOUND?

I think a 6ft barrel was enough to show what a supersonic nerf dart can do. Davekni got a pingpong ball going 2000mph which is 2930 ft/s!! (mach 2.5). His barrel was 20ft long. It can shoot through 3/4in plywood! You can see that video here- youtube.com/watch?v=5xuwu4gjNbQI always thought the speed of sound was the limiting factor, because the flow 'chokes' at mach 1. Its a big controversy among air-gunners, and theres like a 900 post topic on it here gatewaytoairguns.org/GTA/index.php?topic=102604.540. Some guy got one going like 2100 ft/s which I thought was impossible. youtube.com/watch?v=qUq4OQqZ2bw So it prompted me to do some research.It turns out flow does choke at mach 1, but its only the mass flow that chokes. The gas can still expand supersonically.Also a big thanks to Dr. Carl Knowlen from University of Washington, and u/Overunderrated, u/TheQueq, and u/InductorMan from reddit.Here are the papers I referenced:A COMPARISON OF DISTRIBUTED INJECTIONHYPERVELOCITY ACCELERATORS - researchgate.net/publication/268456817_A_comparison_of_distributed_injection_hypervelocity_accelerators Probably the most concise and easily understood!Numerical Evaluation of a Light-Gas Gun Facility for Impact Testresearchgate.net/publication/270629342_Numerical_Evaluation_of_a_Light-Gas_Gun_Facility_for_Impact_TestShows different muzzle velocities for different barrel lengthsTHE THEORY OF HIGH SPEED GUNShttp://www.dtic.mil/dtic/tr/fulltext/u2/475660.pdfProbably the most extensive on the subject "The reader Is assumed to be an advanced student in engineering." I hope you payed better attention in physics that I did.Outro music by MDK, youtube.com/watch?v=2_t5Lm040GwFortnite clip from reddit.com/r/FortNiteBR/comments/8e7vq6/the_fortnite_foodchain
