This is a video that shows the progress training a white lab mouse to learn to push a switch to get food.  This is a Biology project using a device called a Skinner Box to train the mouse.  The Skinner Box was made from a 5-gallon paint bucket and some scrap electrical parts.  The mouse learned fairly quickly and by 10 or 11 days was starting to get the hang of it.  As you can see, by Day 17, the mouse was pretty well trained to hit the swicth and expect a sunflower seed to pop out of the food chute!
