video - Brownian Motion
Purpose:View Brownian motion of smoke particles under a microscope.
Attach AmScope HD Digital camera to top of microscope and place Brownian motion cell on observation plate with side observation window facing you. Place light source as close as possible to cell's window. Light a match and let it burn for a couple of seconds. Squeeze red rubber bulb on cell, blow out match and place next to opening on cell and release bulb. If enough smoke has been sucked into the cell, smoke particles should begin to appear on the screen. Adjustments may have to be made as far as focus and cell placement.
