If you add a tiny bit of sodium bicarbonate to the mix, it reacts with the acetic acid and makes it much less smelly. The product of that reaction is water, which effectively catalyses the silicone curing reaction. It ends up curing faster and stiffer but the downside is that the surface ends up a little moist. Good for moulds, not so great for sticking it to things.

Yeah, I worked for Sugru for 7.5 years as a factory engineer designing/building the machines that pumped/shaped that stuff, I was also involved in mixing the batch ingredients up. I knew Jane very well. Unfortunately, it was always too expensive for most. Obviously, being an employee and an artistic type, I could get access to kilos of the stuff and made lots of arty sculptures with it over the years. The person that invented Oogoo tried to associate it with Sugru and there was some legal shenanigans. The German company TESA bought out the company and the brand several years ago now and Jane has not been officially associated with it for a over a year now. Several years ago Loctite ripped the whole product off, even down to the packaging. Inspite of patents, Sugru could do nothing, Loctite had just tweaked the formula slightly and they got away with it. But Loctite's product simply wasn't the same in terms of it's raw properties and feel. Same with Oogoo. Sugru was/is a much superior product.

@@justtinkering6713 It is activated by exposure to moisture in the air. A tiny amount of moisture is inside the packaging, not enough to completely cure it, but enough to give it a shelf life of about 8 months. Shelf life can be doubled/trebled by keeping it in a fridge/freezer. My memory is a bit sketchy on the chemistry but I believe the moisture activates a catalyst which in turn cures the product. I believe it was this moisture activated catalyst that was the chemical innovation needed to allow it to become a commercial product.

I use this with high temperature permatex gasket maker. I have a mold that's the shape of my heating block on my 3D printer. So the result is that I make a sleeve for the heating block to dampen the cooling effect from the part cooling fans. Works a charm and lasts a really long time - at least a year - before having to make another.

Here is a cool idea regarding 3D printers and this type of silicon-based material. I don't know the feasibility of this, but I would like to explore whether it would be possible. Here is a quick plan I've formulated on this subject: Adapting a 3D printer to work with materials like silicone and corn starch (similar to homemade Sugru) without using heat can be challenging. Standard 3D printers typically use a heated nozzle and extruder to melt and deposit plastic filament. However, using non-heated materials like silicone or corn starch in a 3D printer would require a significantly different setup. Here are some considerations and challenges: Material Properties: Silicone and corn starch have different physical properties compared to 3D printing filaments. They are not readily extrudable like plastic. They may require a specialized extrusion system. Extrusion Mechanism: A different extrusion mechanism, such as a screw or piston system, may be necessary to push these materials through the nozzle without heat. Viscosity: Silicone and corn starch-based materials can be viscous, which might require modifications to the printer's mechanics to handle the flow. Nozzle Design: You would need a custom nozzle designed for these materials, as the standard hot-end nozzle used for 3D printing plastic may not work effectively. Cooling and Solidification: Unlike heated plastic, silicone and corn starch would need time to cool and solidify. The printer would need to account for this in its design. Material Compatibility: Ensure that the chosen materials are compatible with the printer's components to avoid damage or clogs. Experimentation: Adapting a 3D printer for non-standard materials will likely require a lot of experimentation and testing to find the right settings and configurations. Safety: Make sure to consider safety precautions, especially when working with new materials and modifying the printer. In summary, while it's technically possible to adapt a 3D printer for non-heated extrusion with materials like silicone and corn starch, it would involve significant modifications and experimentation. You may also need to develop or modify the software to control the printer accurately with these materials. It's a complex undertaking that requires a good understanding of 3D printing technology and material science.

To clarify. Corn flour and corn starch are not the same thing. Corn starch is often called corn flour, but that is incorrect and they are two different things. Corn flour is made by grinding whole corn kernels. Corn starch is almost exclusively the starch from the kernel.

@Rob I tried doing something similar when I needed to take a mold of the antiskid pattern from my boat deck to be able to stamp it into some thickened epoxy I was going to use to make a repair on deck. All I did was skirt a whole bunch of silicon in a bucket of soapy water, kneaded into a ball inside the bucket, then pressed it onto my boat deck and got the pattern out of it. let it set and had a block I could use to recreate the pattern. Weather all summer was terrible here so still have to make that repair.... but my plan was to put some thickened epoxy in the holes, let it set to tacky, then dab the mould into a bin of powdered sugar so it doesn't stick to the epoxy and stamp and repeat. once it sets, rise the sugar with water and presto... well at least that how it turns out in my head. :) Great video as always.

Very nice.. This is exactly what Im after and your video came at the right time on how to make it yourself. Brilliant. Off topic: I thought I should mentioned if you place rubber tips along each bladed flaps where it folds and where the flaps meets as it closes will not only silence two plastics hitting together like a shock damper, but will also behave like shock spring absorber according to the rubbers spring constant. Therefore as each bladed flaps moves and hits in between where opposing rubbers are position. It will increase the rotors kinetic energy providing substantial amount of torque as it will bounce off away from each other in respect to its propelled swinging motion. Thank you as always

Only downside to the cornstarch method is that the shore strength is pretty high, so it tears easily.

If you want to keep your rubber strips consistant, could you make a form for the ooGoo that would fit over the end of the blades and then line them with baking paper or maybe even a spritz of olive oil and let it cure in the form? Needs water to cure, so maybe after you form it, you can release the form anf if its the right condistancy it should hold its form... 🤔
