I have developed a time machine, where should i go?

i've successfully created a time machine that ACTUALLY works. its a bulletproof idea. I put time crystals inside of a clock then smashed it with a hammer, thus creating a sonic boom that ripped a hole in the spacetime continuim. ( for those of you who believe that a sonic boom cannt tear a hole in space, i reure you that i have amplified the waves with gravity and lasers). i then captures timetrons(time particles) in a cup then placed them on a working cup. i was then able to travel to any time period, just to make sure that it worked, i went to 1776 and helped George Washington defeat the muslims. where else should i go to change history?
