I was in mexico san luis rio colorado, all restroom are located outside , i had stepped out to use the restroom on the way back to the house i noticed something lifting off the floor with no sound. i looked and saw a disc shaped ufo silver/chrome . it went as high as the house then it stopped for like 10 seconds, after it started moving slowly to the right releasing bright smoke leaving a straight trail. it stopped then started moving to the left zig zag type of movement (slowly). it zig zag 5 times leaving behing a trail of bright smoke yellow,orange,red,tan,turquoise, after, it stopped, and it stayed still for like 20 seconds. out of nowhere it started sounding like thunder, next thing it broke the sound barrier from a still point making a ring of air just like the jets. it blasted straight to the sky becoming a small star. i starred at it for 5 min next thing it shot away just like a shooting start. the bright smoke stayed in the air for like 40 min till it slowly went away.
