Ive got a few short videos like this coming up in the next few days! Heres the cool water balloons i used in the video https://amzn.to/2llGiTH Chris's channel & instagram https://www.youtube.com/user/rol36915/featured https://www.instagram.com/chrisrollinsvideo/ amazon affiliate disclaimer: Backyard scientist is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com

I've always wanted to try these experiments! Hope you enjoy :) Sometimes I get comments wondering where I get my shirts and stuff from Hawaiian Shirt Shirt - https://amzn.to/2Ifo1Al Hawaiian Shark Shirt (from ballista video) - https://amzn.to/2MYMG0O 10L Liquid Nitrogen Dewar - https://amzn.to/2IgLJwb Insulated glass bottle - https://amzn.to/2XlRyRC My Camera - https://amzn.to/2WGfx9J Giant Air Plant information: Its scientific name is Tillandsia utriculata. They are called 'air plants' because they typically live in trees. People sometimes think the name means they can survive air alone, but thats wrong! they still need water and nutrients (typically from decaying leaf litter they collect). They don't have a very high survival rate on the ground, and tend to die from staying wet for too long. Im just trying to raise awareness because I see people throwing them out or mowing over them all time time and there are very few left in my area. https://entomology.ifas.ufl.edu/frank/savebromeliads/floridas-bromeliads/Tillandsia-utriculata.html https://www.morningwoodgrowers.com/about-us/endangered/tillandsia-utriculata-aka-giant-wild-pine.html amazon affiliate disclaimer: Backyard scientist is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com.

Hey everybody! Ive wanted to make one of these forever. Well, i have made one before but it was not a 'good' fresnel lens. If you want to learn more about fresnel lenses this is a good website - https://rimstar.org/equip/fresnel_lens.htm They have a youtube channel too with lots of educational content. https://www.youtube.com/user/RimstarOrg And of course shoutout to The King of Random where i first saw this idea ! https://www.youtube.com/watch?v=jrje73EyKag

I still had 2 gallons of glue from the last glue trap video, so I thought this would be a great way to use the rest of it! I forgot how gross the glue really is though, I practically need to shower in WD-40 to get if off. 😰I had to re-upload because it was stuck on 360p but its working now!

I got a lot of feedback from my last video. Now the table saw is back with FULL AUTO more explosions, and i shoot randy. Table saw vs christmas ornaments, oobleck, fish tank, balloons, and soda.

This is what happens when you ignore the warnings on a Lithium (LiPo) Battery. First I tried Disassembling the battery to learn about it. Then I tried shocking the battery with a tesla coil. Surprisingly that did not work, so I connected it to a car battery to overcharge it and it worked great. Of course, by working great i mean it caught on fire. Finally I incinerated the battery with a 30W infrared laser in a fishtank filled with 100% pure oxygen.

I saw this video on reddit and was suspicious it was fake. I thought if you pew pew your phone it would instantly break, so I decided to try it to for myself! Reddit link https://www.reddit.com/r/Whatcouldgowrong/comments/9ejgcv/wcgw_if_i_play_with_a_gun_on_instagram_live/ Ok guys, no insults or personal attack will be allowed in the comments. keep it clean. this video is a learning example for following the rules of handling a gun, not a witch hunt. #1 THE GUN IS ALWAYS LOADED. dont play with guns. don't point guns at stuff you don't want to shoot. https://www.instagram.com/backyardscientistofficial/ https://twitter.com/ChemicalKevy the gun - https://www.pyramydair.com/s/m/Hatsan_AT44_10_Long_QE_Air_Rifle/3390 KEEP READING! The phone can not record to the SD card or internally fast enough either. I filmed the second shot from the phone, and the video is corrupted. I used a free app to preview the file, and it does not show the last few frames before i shoot the gun. here is the file. https://drive.google.com/file/d/1nzQonW9JhQny5HWE8UpWnDfmWjcFZcdY/view?usp=sharing use mp4 fixer on android to view the file if you want to see for your self.

I had a bunch of fun at Maker Faire NYC! I saw a lot of really neat builds, tools, workshops and displays, but the rubber band whip really stood out as something easy and fun anybody can do. Maybe im still a 12 year old at heart but I think this thing is a blast. And it breaks the sound barrier WITH RUBBER BANDS!

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!

Giaco Whatever video: https://www.youtube.com/watch?v=BrtBc-9pQv4 A few more thoughts on the Nerf Cannon. Yes, I know if I used a longer barrel I could get higher speeds, but I did not want to deal with a 20ft long gun. 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- https://www.youtube.com/watch?v=5xuwu4gjNbQ I 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 https://www.gatewaytoairguns.org/GTA/index.php?topic=102604.540. Some guy got one going like 2100 ft/s which I thought was impossible. https://www.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 INJECTION HYPERVELOCITY ACCELERATORS - https://www.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 Test https://www.researchgate.net/publication/270629342_Numerical_Evaluation_of_a_Light-Gas_Gun_Facility_for_Impact_Test Shows different muzzle velocities for different barrel lengths THE THEORY OF HIGH SPEED GUNS http://www.dtic.mil/dtic/tr/fulltext/u2/475660.pdf Probably 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.
