I love rockets. Planning to build a tin rocket but not with water and air pressure. I would like to build a small metal tin rocket using fuel as RP 1 and oxidizer as LOX. I know this is too hazardous please don't try this. Is that possible to build a metal tin rocket with the same fuel used in real rockets?

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Questions about dangerous amateur experiments, such as constructing your own engine or propellants are off-topic. Rockets and their propellants are INHERENTLY DANGEROUS and can pose hazards to not just yourself, but others around you (friends, family, neighbors, etc). It may also be illegal. Please see this meta post for more information." – DarkDust, uhoh, GremlinWranger, Jan Doggen, Boosted Nub
- the heat of combustion would soon melt your plastic bottle. RP/LOX rockets use special high-temperature metals like Inconel, and then still need to cool the nozzle to prevent melting.
- a plastic bottle becomes brittle when you try to store LOX in it, it's unlikely to be strong enough to hold the LOX at any pressure
So we'd be talking about a different kind of rocket here: one built from metal, using two tanks to hold the LOX and RP, and with a combustion chamber to mix and ignite them.
The next step up from a bottle rocket is not LOX/RP. It's an Estes solid-fuel rocket.
