Is putting something in a blender a physical or chemical change and how ?

Physical because you are not changing the substance chemical way in other words youre not changing the compond of what its made out of you are just bending it. but if you blend it with something else for exemple a bananna with a strawbery you are changing its structure wich would be chemical.

Physical if you will not turn on the blender.
chemical if you will turn the blender on and mix the ingrediants 

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade
