Thanks for watching the video! Lol I wasn't too worried, Titanium sparks aren't as bad as they look, and it was raining all day here so the whole tree was soaked. I just wonder what my neighbors thought when they saw that🤣.
It's called Falling Leaf fuse from CannonFuse daught Kom (spelling altered to keep the YT bots from deleting my comment), it's typically cut into multiple short lengths and loaded into mortar shells to produce trails of sparks and light, it has a very slow burn rate (I think about 45 seconds/foot) and like you said it produces a very brilliant light when burning, it's much brighter than standard Visco fuse. It is a little more expensive but it can add a nice effect to some fireworks.
Where are you ordering from? And how big are your motors going to be? My favorite source, The RCS Store, has standard HTPB, low molecular weight HTPB, and standard HTPB with CAO-5 antioxidant and HX-752 bonding agent premixed in it. The low molecular weight HTPB is good for pouring large motors, it's thinner and requires more MDI Catalyst, which ends up making it even thinner when mixed, but it's more expensive, while the CAO-5/HX-752 blend is meant more for long term storage and is also more expensive. If you're new to APCP, I'd recommend the standard HTPB, it's all you need to make basic rockets without all the bells and whistles needed for more advanced rocket motors. Just don't buy a 50/50 ratio of resin to MDI Isocyanate curative like I did, it mixes at 87/13 lol.
Christ I hate UA-cam censorship... I had a nice long explanation of the three grades and youtube didn't like it somehow, I'm so fed up with them. The short answer is just get the basic HTPB, you don't need anything fancy. R C S rocket motor components has three different ones, don't bother with the low molecular weight or antioxidant ones until you are making bigass motors or motors that will sit for 6+ months.
@@Wilqu_44 I'm sorry to break it to you but from what I've heard from other European rocketeers it is not sold in any stores or shipped from any websites to your area. Fortunately you _can_ make it yourself if you are dedicated to making rockets though, but it's not very easy or fast. Do an online search for ammonium perchlorate electrolysis cell, search a bunch of rocket forums and websites and UA-cam videos and you will find lots of info on the process. You just need a voltage source like a DC power supply, some plastic or glass tubs, some graphite electrodes and a couple platinum coated steel electrodes for the final process of oxidizing chlorates to perchlorates. If I remember correctly the starting materials are cheap and readily available but I haven't looked in a while to see what's available in your area, so do some digging.
@@TheExplosiveGuy And one more thing would it be possible to make KPCP (Pottasium perchlorate composite proppelant). it is the same recipe as for APCP only that, instead of ammonium perchlorate is potassium perchlorate. I have not tested this and it is a very interesting recipe for me because potassium perchlorate is much easier to make using electrolysis then the double Metathesis reaction. 70% Pottasium perchlorate 20% HTPB resin binder 10% 2-3 micron German Blackhead Al powder 10% coarse Titanium granules/what color you want e.g. Cuo for blue color.
@@Wilqu_44 I've never tried it but it may work, it won't have the impulse of AP since it's reaction product contains more solids but it's worth a try, just be careful when mixing, since it is essentially flash powder, I'd suggest mixing the resin into the KCl04 first then add the aluminum afterward. I would also suggest starting small and testing it remotely to make sure it can't detonate somehow, I doubt it would but it's best to be safe than sorry. Let me know how it turns out, you've got me curious...
I have a high school bottle rocket project coming up and want to use ammonium perchlorate and aluminum I prob won’t need all the other stuff. But do you think i will need the HTPB and the MDI isocyanate or just use normal resin? After all this alone would probably beat out all of my peers. To make the rocket I was gonna take a 7.5 oz coke (very tiny one) and cut the top. Then plaster high temp sealant or resin for the walls so the fuel and stuff won’t react with the aluminum can. I would then do like you did and push the fuel and stuff in there. I would also cut slits in the can to pull together to form a nozzle. How big do you also think the nozzle should be so it doesn’t implode. I would love some feedback for this so I don’t screw it up or make a bomb accidentally
It won't become a B**b, however the pressure is too high for an aluminum can, Try using a better & stronger case (like the thick 2.5~3mm wall paper tube in the video) if you have to use aluminum can on the outside....
@@jacks19822 yea, I mean I talked to some other people about this they said a definite no. I would still like to do it I don’t think it would implode as long as the nozzle is a good size. Maybe I can put the wall paper tube inside the bottle or something, I would have to get it approved with the teacher aswell. If it doesn’t work out I’ll just do a normal water rocket.
@@garfield_thedog1188You can test it in small batches at home first... Sorbitol (KNSB, Nakka.) + 10% aluminum is powerful enough for most purpose. You have to understand, the objective of the project is not to FAFO, but to show your understand of rocketry & your love of science. Rocketry and space is where you'll find jobs, or build your own company 10~20 years down the road, there'd be almost no other jobs left after A.I. taking over.
@@garfield_thedog1188 Hey sorry I missed your comment, sometimes youtube glitches and doesn't send me notifications. Like the other fellow stated, aluminum cans will 100% not work (ask me how I know😂), APCP burns incredibly hot and will melt them instantly. A thick cardboard tube will work much better, and a 25/75 mixture of fine crushed sand and bentonite (standard kitty litter is made of bentonite, get the cheapest unscented stuff you can find) makes great nozzles, it has to be formed with a mold and packed with either a hammer or hydraulic press. There are lots of videos on how to make kitty litter nozzles here on youtube, they're cheap and easy. But I would honestly recommend you not attempt an APCP rocket until you are thoroughly familiar with sugar rockets, jumping right into APCP is dangerous, it is _not_ a beginner fuel. There are also tons of videos on how to make sugar rockets, they'll teach you the basics you need to one day achieve the knowledge needed to make APCP high performance fuels. APCP rockets are amazingly good at turning into pipe bombs if you make just one mistake in your manufacturing process, I would suggest spending at least one year studying everything you can about rocket basics, you need to know about Kn ratios (the ratio of burning surface area to nozzle orifice area), burn rate exponent, air bubble entrapment, component grain size, grain liners, grain shape, grain bonding, grain type, igniters, motor casing selection, high temperature nozzles, the list goes on. They seem simple at first glance but they are most certainly not simple. Hit me up if you have any questions or want some input on anything, I'm happy to help a fellow beginner rocket enthusiast.
@@TheExplosiveGuy thanks for the info, the project already passed and we HAD to use water. Did pretty well, I do hope to do more with rockets in the future just gotta ease into it more.
Rocketmotorparts dot com, thanks for watching! Edit: if you get some don't buy a 1:1 ratio of HTPB and MDI Catalyst like I did, it mixes at an 87:13 ratio, so buy a gallon of resin and the 32oz bottle of MDI Catalyst, or you'll be stuck with way more MDI Isocyanate than you need.
APCP is the type of rocket fuel I'm using (Ammonium Perchlorate Composite Propellant) while HTPB is the polyurethane binder used to hold it all together (Hydroxyl-Terminated PolyButadiene).
70% Ammonium Perchlorate, 20% HTPB resin (87/13 HTPB/MDI catalyst), 10% 2-3 micron German Blackhead aluminum powder, plus an additional 10% Titanium granules for sparks. There's more detailed info in the description, if that doesn't answer your questions feel free to ask.
@@TheExplosiveGuy anyways..can you suggest what would i do. i i used to mix whistle rocket..my comp..was kclo3,sodium benzoate,red iron oxide and parafin wax...after i put it into a tube and press using hand clamp presser then try to ignite it..surprisingly did not whistle and flew up but an explotion happened...what was i did wrong?
@@denzouatiro I know exactly what went wrong, it wasn't rammed hard enough. Whistle rockets require a hydraulic ram to press them, they need a couple thousand PSI of pressure to fully compress the components into a single solid piece, any air gaps, cracks or porosity will always lead to an explosion. You can make your own ram from a cheap hydraulic bottle jack from a car and a couple 4x4 boards and a few strips of steel and bolts, but make sure you drill and tap a threaded hole in the high pressure side of the jack for a pressure gauge to read how much force you exert, if you go too far it can explode. Look online for the formula to calculate how much pressure needs to be applied to the fuel (there's a few pyro websites with the info, I can't remember them off the top of my head), based on the diameter of your bottle jacks piston and the diameter of your whistle rocket ID, it will determine what pressure you pump it up to. Be careful with whistle rockets though, even if they're properly pressed they can CATO, the fuel is basically flash powder. And remember to press the material in small stages, a little fuel is added, you press it, then add a little more fuel, then press it, and so on, until you get to the bulkhead, or only the top and bottom will compress while leaving a fluffy uncompressed CATO waiting to happen. And one other thing, you need to support the tubes while hydraulically ramming, or they will split from the pressure. You can use stainless steel hose clamps along the entire length of the tube, it's a pain screwing and unscrewing the dozen or so clamps it takes to support the entire length of the tube but it's the cheapest way.
i like that you showed the entire process :) (also, i thought that the tree would catch fore at the end there, lol)

0:35 is this HTPB?
Yes, the clear resin in the cup is HTPB, the cloudy resin in the bottle is MDI Isocyanate curative, mixed at an 87/13 ratio.
Can I ask what grade of htpb resin do you use for propellant? I'm having trouble ordering online because I'm being asked what grade you need 😅
