Give me ideas.
The first thing I would do if I ever traveled back in time would be to teach Brazilian Jiu Jitsu. That would blow their minds, whoever they were.In the 1500's you might just be burned as a witch if you claimed to be a time traveller. So careful what you wish for.
The problem with that is that you have maybe five hours of battery time, and a limited amount of anything like body wash. The ingredients on the bottle don't mean anything to people from then, so it would be nearly impossible to replicate it. Google Translator won't work without an internet connection, and even if there was an offline version the translations it provides are shaky at best with modern languages, and the dialects from back then would be entirely different.I also see this being a one way trip, because anything you do or say then will change the time stream. Even if you did travel forwards in time to the date and time you left, the world could be entirely different than what you left, leaving you at best out of the loop on 'current' technology and customs, and at worst a completely foreign individual with no connection or knowledge of anything that is going on around you.I think that,I would take my laptop and mobile and also photos and also some items like bodywash and other things which can fit inside the time travel machine. I think, showing them this and also could use the google translator which could help me in learning about them as well. Showing them these bits of technology will show that I am from the futurre and what will happen later on and will be amazed as well at the techology which can improve the lives of people.
