saw another object flying lower than the plane and much faster, heading NE. Object white and shaped like a Mentos

I was in my backyard with my toddler and baby. I was sitting with the baby in the shade and my toddler was playing in her sandbox. I saw an Airplane flying southeasterly and pointed at it to show her. I looked at her to see if she was looking in the direction I was pointing and when I looked back at the plane I saw another object flying lower than the plane and much faster, heading northeasterly. The object looked white and shaped like a Mentos. I did not observe it for long due to trees in my field of view nor was there any time to document it with a video or photo.
