1. Fill one third of the bottle with honey.
2. Fill the next third with oil.
3. Fill the last third with water.
4. Wait for all three liquids to settle.
5. Drop in the coin, grape and cork.
All three items (coin, grape and cork) end up in each
of the three different fluids (honey, oil and water). Each liquid
and item have different densities and stay in a separate layer according
to its density. The most dense is at the bottom and the least
dense is at the top.
