Giant Hamster Wheel and Other Projects My Students Made sciencetoymaker 2022-03-18 | Back in the 1990s my Jr. High students made interactive exhibits for a local children's museum. Here we invited kids from the elementary school next door to come over and test them out. I had some pretty rough students, but they rose to the occasion of becoming teachers for the young kids. Although I was terrible at classroom management, all behavior problems ceased because they had a productive way to get attention.

For a more advanced Dragonfly Helicopter that you make your own propeller from a 2-liter bottle, click here. youtu.be/XjOp9fw3L9w0:00 (1) Introduction0:42 (2) Let's Get Started Put a propeller on a balsa stick. Hold it close or else this might happen. (there are a few extra sticks if that happens)1:08 (3) Rubber Band Cut a piece 28 cm or 11”. Use sharp scissors to cut. Nonstick scissors (Teflon coated) work especially well)Tying is easy, but confusing at first. The overhand is the simplest knot there is—just make a loop and put the end through. But we put the two ends together and treat them like one strand.(By the way, mountain climbers know this as the European Death Knot!)2:02 (4) Hook the Rubber Band The knot always goes in the back. (because it tends to get caught on the fuselage) 2:36 (5) Make the Wings 3:54 (6) Wind Up the Rubber Band Your helicopter will go higher if you dab some soapsuds, liquid soap or shampoo right here to reduce friction.Most people do not wind enough at first. The first 50 or so turns don’t do much. You can wind more than 150 turns.4:23 (7) Alternate Paper Wings Paper is heavier than foam and not as rigid, so it is not rigid enough to stick out far away from the fuselage. But these paper wings with lots of surface area compensate. Note that paper becomes very limp and weak in humid weather. It might stop working once it absorbs moisture from the air.If this project works well for you, please help spread the word about a good hand-on science project. If it is not working well for you, communicate with me about what’s happening so we can solve the problem.

Eco-Empirical Dragonfly Helicopter Build sciencetoymaker 2016-12-10 | IMPORTANT UPDATE: Since making this video, I made another video for a design that is a bit simpler and uses more"off the shelf" parts (except the rubber band--school/office rubber bands just don't work well). It is not variable-pitch like this EE design, but for most people the newer version is better. So I no longer have the Eco-Empirical kit listed on the Dragonfly Helicopter store page. If you really need to make a variable-pitch helicopter, contact me.

Walkalong Glider Gathering 2015 sciencetoymaker 2015-07-24 | Follow us on Facebook goo.gl/3R1SwJGoogle+ goo.gl/igYDtwFor a few days in July of 2015 there was a gathering of walkalong flight enthusiasts and friends. Phil Rossonin (literally wrote the book about walkalong gliders) traveled from Boston; Mike Thompson (engineered thin foam gliders and freewheeling props, invented Jagwings) from Wisconsin; we all traveled to Ithaca to join Erik Herman. Later we went to the Piper Flight museum in Lock Haven. This video shows some of the things we did.Start: Mike makes walkalong glider history—or is it bike-along?0:12 Michelle and Ken Kontenaar kindly put us up for the night and Michelle—who is the Director of Education at the Sciencenter in Ithaca, New York—took us flying. My daughter, who is sciencetoymaker.org techie, accountant and helper also came along and is seated in the front-right of the plane. Emily Cotman was running a cool engineering summer camp that we participated in at the Sciencenter. Unfortunately, as per Scienceter policy, we could not take pictures.0:19 In the afternoon we worked with kids in Barton Hall at Cornell. I got footage of Jagwings for an upcoming video. Rather than take lots of cars and have to deal with lots of parking permits in the Cornell University campus, Erik drove us in on the Physics Bus. Sadly, I did not get any video of that. 0:24 We also tested air rockets that you send up high, where they release auto-gyro helicopters that glide back to earth. A video about that will be coming soon, too. 0:32 The kids launched water rockets without water since we were inside, which makes a loud shock wave at launch. We made gliders with the kids and showed them how to fly all sorts of designs. 1:34 The next day we were in Lock Haven Pennsylvania, at the Piper Museum where Marshal Hopkins was running a summer camp. We made and flew flight project with kids in the great hanger. 3:29 Sadly, Phil had to leave the next day. Mike stayed on and we collaborated on a video about how Mike makes those cool freewheeling propellers for walkalong gliders—yet another video that will out soon. We had a wonderful time! Last time we got together was at the St. Louis Science Center goo.gl/YKblVT

Jersey Shore Science (and Other Stuff) Road Show 2007 sciencetoymaker 2015-06-05 | This started out as a science road show. With the abundance of apples we included harvest activities-- cider-making and peeling machines. My wife came and taught origami, adding a cultural element. So I don’t know what to call it, but it was fun as well as educational. Thanks to Mrs. Heather Reeder’s (the other technology teacher at the middle school) organizational ability, lots of 8th grade teenagers were able to help out all day at all three of the elementary schools. So instead of being a stage show with the whole school passively watching an assembly, it was truly interactive. The teenagers worked through the whole day, one grade at a time. They taught the elementary school students in small groups, demonstrating and explaining what was happening. Some of the (male) helpers are not angels in school, but we made it clear that this event was about service and they rose to the occasion. I’m very proud of them. Instructions for building many of the science activities can be found here http://www.sciencetoymaker.org .If you want to more specific information about projects/activities click http://www.sciencetoymaker.org/VidIndex/roadshow.htm The music is by my favorite living composer (and harpist) William Jackson. The songs are from his Duan Albanach CD, which more people should know about. Words fail me in trying to describe how much William Jackson’s work means to me. Dual Albanach commemorates pivotal events which shaped the history of Scotland and I thought it also captured the liveliness of the road show.

Envelope Walkalong Gliders sciencetoymaker 2015-05-12 | Update Aug 2018: Sorry we don't sell this anymore. Too often gliders were crushed in the mail. Using gliders made from thin, low-density EPS (expanded polystyrene) is the best way to get started. http://bit.ly/2Pk6V5U(Original description)The easiest way to get started with air-surfing is with an inexpensive envelope containing a variety of gliders. Thin foam gliders are much lighter than paper so they fly very slowly, giving you time to think. Sciencetoymaker teamed up with high school acting students to make learning to fly fun.

The concept has been around for a generation, goo.gl/ZXpjPLyet it remains almost unknown. There is a reason for that. Although walkalong gliders are not difficult to make and fly, getting people through the FIRST STEP has been difficult. My obsession for the last 5 years has been to get my students' heads into the sky with their feet on the ground--flying as a hands-on science activity. We started with paper gliders but switched to very thin foam, recycled from packaging, which has superior strength to weight ratios. Then we found foam that was even lighter. Finally, we have gliders so efficient and slow-flying that people can be flying within minutes. Almost all the people in the video had not known how to fly 5 minutes earlier.The best way to start is to buy a box of foam that also has a couple of ready-to-fly gliders. It's not only that you can start flying very quickly; knowing how the gliders are made and flown then makes it easier to make your own. The proceeds from the sales go to a nonprofit Physics Factory goo.gl/PpjT9x1.) The numbers correspond to the numbers at the top of the screen in the video.2.) The easiest way to start out is buy a box of foam which includes some ready-to-fly gliders. Open carefully and save the box for protective storage and transport.3.) This is special very low-density foam which is unbelievably lightweight. It is recycled, originally used to cushion imported furniture. We hotwire cut it on a homemade robotic CNC machine to perfect half millimeter slices. It is also very delicate to handle. You can wreck it without trying. 4.) Although the gliders have been tested and are ready-to-fly, we have to bend the front wire weight flat for shipping. Just bend it 90 degrees, but be very gentle as you handle the glider. If you don't bend it forward, the glider will probably stall rather than fly forward. If the glider still seems to stall too much, you can bend it forward even more. This shifts the "center of gravity" (balance point) forward in the glider. Opposite, if the glider dives, then you can remedy diving by bending the wire backward, which shifts the center of gravity backward.5.) For launching, make sure that you are holding the glider right side up: the wire bends down. There is a little downward bend at the front of the wing. This front wing bend is called camber and it creates an airfoil shape for more efficient flying. At the back of the wing are 2 flaps that bend 45 degrees up, called elevons. They keep the glider from diving.You hold the glider gently from the back. Notice that there is a thumb and finger below, and just one finger above the glider. This keeps the glider wings slanting up just a little. This upward slant of the wings is called "dihedral", which all airplanes have for better stability.Caution: some people unconsciously hold the glider in a way that makes the wings droop down (anhedral). If the glider wings do not spring back to dihedral, then the glider will not fly.THIS IS ALL I CAN FIT IN THE YOUTUBE DESCRIPTION BOX. THE FULL TEXT IS HEREgoo.gl/PGFdAn
