Proving the density equation! ρ = m / V | Live Experiments (Ep 21) | Head Squeeze

From the creator

Jon Chase explains what density is and proves the formula 'density=mass/volume' works by manipulating the values in this fun demo.

The items you need to get started are: a few cans of lemonade or another soft drink (diet AND full fat), digital scales, a jug, a pint glass, a small container to capture displaced water, a small sealable plastic container, 16 two pence pieces, white vinegar, bicarbonate of soda and some tissue paper. Experiment #1 1. Fill your pint glass or large jar up with water 2. Put the pint glass inside your container to capture the displaced water 3. Submerge the can in the pint glass 4. Now weigh this excess water on your scales 5. You can now deduct the weight of the can to get the figure for the displaced water Experiment #2 1. Put some vinegar on one side of your small sealable container. Now put a small amount of bicarbonate soda on the other side (separate the
