Making explosives is not only extremely dangerous, it is highly illegal without a number of licenses. With airsoft type activities, the energy is any airsoft device is kept quite low to prevent injury- trying to make your own may produce something with too much energy, resulting in injuries you did not intend. Not recommended that you try this.
No. Not without a license.
You can't without some experience in metalwork.
Whale parts are not used to make explosives.
No, Type S mortar cannot be used without sand. Sand is a key ingredient in mortar mix as it helps provide the bulk and strength necessary for proper adhesion and workability. Omitting sand would result in a weak and unworkable mortar mix.
Gravel is added with mortar to make concrete.Another answer:Cement is mixed with just water and perhaps some fine sand to make mortar. Gravel or rocks, strengthening agents in load bearing concrete, can interfere with mortar in that mortar needs to work something like an adhesive.
I would highly recommend that you do not make your own airsoft pellets. They might jam and or brake your gun.
its used to make explosives ;)
dont let them make contact with the snow or find some sort of cover for the gun.
That depends on where you are and what kind of explosives you make. The ATF redefined the word 'explosives" last year to include several products that were not previously considered explosives. In many places you can make your own black powder, rocket propellants and fuse. Some more powerful "explosives" can be made in very small quantities for use in fireworks, but there are restrictions on the storage of explosives.
