Getting stuck in the negatives (and how to get unstuck) | Alison Ledgerwood | TEDxUCDavis

Alison Ledgerwood joined the Department of Psychology at UC Davis in 2008 after completing her PhD in social psychology at New York University. She is interested in understanding how people think, and how they can think better. Her research, which is funded by the National Science Foundation, investigates how certain ways of thinking about an issue tend to stick in people's heads. Her classes on social psychology focus on understanding the way people think and behave in social situations, and how to harness that knowledge to potentially improve the social world in which we all live. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

How To Make Sugar Rockets

How to make hobby rocket “sugar motors” using sugar and kitty litter, that shoot up over 2,300 feet high, and cost less than $0.50 to make.

This video is mainly for educational and demonstrational purposes. If you’re going to attempt it anyway, I highly suggest contacting local rocket clubs to become familiar with local laws, and how to stay out of trouble with the FAA, and avoid hurting any people or property. Playing with unstable rocket motors could result in serious injury, property damage and/or legal ramifications. Use of this video content is at your own risk. You should be aware that misuse, or careless use, of rocket propellants or ignition of an incendiary or explosive material may not be legal in your area. Check local laws and inquire with local rocketry clubs on how to safely make and launch sugar rockets. Music By: Scott & Brendo (“Reverie” – Instrumental) http://bit.ly/ScottBrendoiTunes Project Inspired By: 4 years of testing and experimenting with sugar rockets, and recently a lot of influence from the book “Easy PVC Rockets” by Jason Smiley. (http://bit.ly/IBEasyPVCRockets) If you check out the link, please share the love and let Jason know that Grant Thompson sent you. 🙂 Thank you! My friend NightHawkInLight also has an awesome video on a different method of making a cored rocket with black powder. You can see that here: http://bit.ly/IBBPCoredRockets Project History & More Info: After making my video on Homemade Rocket Fuel (http://bit.ly/DIYRocketFuel) I had a lot of requests on how I built the one that launched at the end of the video. Although that rocket motor worked very well, I wanted to get the process down to a science before making a video about it. This project video shows a slightly different approach to the sugar motor using the same ingredients, and a demonstration of how the rocket motor performs. The main difference is that this is rammed powder as opposed to caramelizing the sugar mix. Sugar rockets are the slowest burning of all rocket fuels, and it's highly unlikely that PVC will explode when using kitty litter plugs and sugar for the propellent. In all my destructive testing, and controlled attempts to get one to fail catastrophically, the PVC was never damaged. All that would happen is that the plugs would blast out. Saying that, I wouldn't use PVC with black power rockets. That is a different story altogether. These motor blasted up over 2,300

This project should only be attempted with adequate knowledge and training, proper protective safety gear, and in a fire resistant area with adequate ventilation. The sparks flying from the foundry can ignite fires, and the fumes from burning dross can be toxic. Use caution and common sense. Use of this video content is at your own risk. Music By: Scott & Brendo ("Feel It" – Instrumental) http://bit.ly/ScottBrendoiTunes Project Inspired By: This foundry is an original design, which comes after months of experimenting, and over 10 different prototypes. The functionality is founded on ideas I collected while searching the internet for different furnace designs. Project History & More Info: For this project I experimented with 10 different prototypes, to develop a reusable backyard foundry that melts aluminum soda cans easily and safely. I tested different refractory recipes, different containers, different setting for blowing air, and different types of makeshift crucibles. I tried various ratios of portland cement, sand, perlite, plaster of paris, water, and even kitty litter. For containers, I experimented with clay pots, plastic buckets, no container, cinderblocks, and a galvanized steel pail. I ended up favoring the galvanized steel pail, and a mix of 50% plaster of paris, and 50% play sand, by volume, which was inspired by a video by NightHawkInLight "How to Make a Soup Can Forge" http://bit.ly/IBSoupCanForge Depending on where you get, or find, your materials the cost can range anywhere from $5-$25 per unit. With the materials I used, I was able to make 2 units for under $40 ($20 each). Even on the high end, this is probably one of the cheapest, reliable, backyard foundries that can be made. I used mine to melt soda cans, and extract the aluminum for future metal casting projects. All the soda cans came from a local recycling depot. I bought back 30 lbs from the depot to avoid having to drink gallons and gallons of soda. 🙂 I stored the ingots in various forms, which you can see in the video"Melting Cans With The Mini Metal Foundry" https://goo.gl/pTP1uG The technique for making the sword in that video, and the gun in this video is called "Lost Foam Casting" and will be demonstrated in

Music By: Scott & Brendo “Somewhere” http://bit.ly/ScottBrendoiTunes See their YouTube page: http://bit.ly/YTScottDW Project Inspired By: SFHandyman's Instructable article: http://bit.ly/IBSFHandyman Project History & More Info: Who doesn't love gummy candy, and who doesn't love LEGO? 5 years ago I was fascinated with it, wondering how it was made, and what gave it its gummy texture. It feels so good on the teeth to bite into it, and my kids go crazy for them .. so I spent a bit of time researching how they're made commercially. My biggest motivation for doing this was to see if we could make our own at home, and I'm actually still trying to figure out how to make gelatin and corn syrup from scratch, so if I can figure out how to do that, maybe I'll show how to do it in another project video. Only a small handful of you have ever seen the LEGO Gummy video I made in 2010, and that's because it was nearly 5 years ago, before I really got serious about making videos. I took it off my channel in 2012 because I had full intentions of making a better version, so here it is .. 3 years later! 🙂 Now I wanted to make candies that made people look twice, and LEGO bricks instantly came to mind because what's more awesome than LEGO and gummy put together? But I wasn't sure where could you get a mold for making LEGO bricks. Surfing around the internet, I stumbled across an awesome Instructable by SFHandyman: http://bit.ly/IBSFHandyman To my amazement, not only had he shown how to make a mold for making LEGO candy, he also made LEGO gummies as well! I played around with loads of variations in recipes to see what texture and tastes I liked the best. And I've kept experimenting off and on for the last 4 years, using my kids and wife for feedback. They gobble them up no matter what variations I use, but I've finally settled on 1/2 cup of very cold water, 1/4 cup of corn syrup, 2 packets of unflavored gelatin, and 1 pack of Jell-O. I've found that the corn syrup seems to help smooth out the texture and the taste. If you
