More fun school stuff, no math involved.

This is another lab from earlier last week. We were learning about presumptive blood tests.
The first presumptive test I used was Bluestar, to test and see if there was in fact a blood sample here, as the pictures below shows, yes, there are two small spots of blood. The Bluestar reaction results in making the blood luminescence a bright blue color.

This is the same area, just zoomed out a little to get a good perspective.

This is the same picture, just with the lights on, kind of weird, you cannot see the blood, but Bluestar says it was there.

Hemastix. This is another blood presumptive test.

Let’s check the spot and see what happens.

Green means go. Positive for blood, something must have happened here.
