MORE FUN TO BIOLOGY DISSECTION CLASSES: TURN A REAL MOUSE INTO A COMPUTER MOUSE!
Here comes a cool tip for the Biology teachers. Instead of those boring dissection classes that simply to cut apart some mice or roaches. Why not add some fun and combine it with little eletronics and mechanics to turn a dissected mouse into a real computer mouse? The little DIY tip that can spice up your class and make it more lively and geeky. More tips and pics for you after the jump!
Obtain a small travel-size (hardware) mouse. This one is a wired mouse that is way to small to use comfortably every day, but perfect for going inside of a mouse. Obtain a similarly-sized (wetware) mouse. These are commonly available fresh or frozen from pet stores, or any other place that sells reptile food. It’s easier to fit a small object into a large mouse than a large object into a small mouse, so err on the side of caution. You can always fill extra space with cotton balls. If you’ve got an optical (hardware) mouse, make sure to choose a pale-furred (wetware) mouse for lightest skin pigment – this will be important later
