    how to make rocket fuel first get sugar and put it in a heating pan and now you want to get potassium nitrate, mostly found in fertilizer put that in the mixture. make sure to keep the pan heated while stirring until it looks like a chocolate cake then you want to pour that into your tube of rocket fuel done! if you want a more efficient type of rocket fuel, get a heating pan and put rust powder and sugar inside mix until done. Please make sure you search up the required amount of each substance before doing so. 9:13 example of what can happen

Not to mention they always have their tools and such with them in their trunk so they can bring the hospital right to their patient if they can't bring the patient to the hospital

    What you called the center support on the door is actually what is called an intrusion beam. These beams are made of at least high strength steel, and I think some cars use ultra high strength steel. The intrusion beam is the main structural strength for doors to protect passengers from severe side impacts. That was impressive to see the knives actually cut through it. I thought for sure the knife was just going to shatter when it hit the intrusion beam but it sliced through it like butter.

    You could torch the blade's spine red hot till a magnet won't stick then air cool and it will be softer to soak-up the shock.
    Also the same treatment works to soften a small area of hardened steel so you can drill it if it is too hard for your bits. I've got stuff that shrugs carbide unless you take some temper out.
    Diferential hardening for shock is the same reason why an ax is soft except for an edge that's a different metal slotted in. That and durability from a hardened edge.

      Metal Tempering
      Tempering is done to develop the required combination of hardness, strength and toughness or to relieve the brittleness of fully hardened steels. Steels are never used in the as quenched condition. The combination of quenching and tempering is important to make tough parts.
      This treatment follows a quenching or air cooling operation. Tempering is generally considered effective in relieving stresses induced by quenching in addition to lowering hardness to within a specified range, or meeting certain mechanical property requirements.
      Tempering is the process of reheating the steel at a relatively low temperature leading to precipitation and spheroidization of the carbides present in the microstructure. The tempering temperature and times are generally controlled to produce the final properties required of the steel. The result is a component with the appropriate combination of hardness, strength and toughness for the intended application. Tempering is also effective in relieving the stresses induced by quenching.
