    Physical properties of Hydrogen gas :

    Density (0 °C, 101.325 kPa) 0.08988 g/L

    Melting point 14.01 K (−259.14 °C, −434.45 °F)

    Boiling point 20.28 K (−252.87 °C, −423.17 °F)

    Triple point 13.8033 K (-259°C), 7.042 kPa

    Critical point 32.97 K, 1.293 MPa

    Heat of fusion (H2) 0.117 kJ·mol−1

    Heat of vaporization (H2) 0.904 kJ·mol−1

    Heat capacity (25 °C) (H2) 28.836 J·mol−1·K−1

    Chemical properties of Hydrogen gas :

    Hydrogen is the most flammable of all the known substances. Hydrogen is slightly more soluble in organic solvents than in water.

    Many metals absorb hydrogen. Hydrogen absorption by steel can result in brittle steel, which leads to fails in the chemical process equipment.

    Seems easy enough. Write up a storie if your travels as if you were a molecule passing threw. Example; you could say first of All you were in a stream and explain all if the places you travelt, then you went threw a filtration system, a bottle factory, into a glass, drunk, go threw the body, being passed threw, flushed down a drain. Maybe absorbed into the earth, got sucked up by a plant, then go on to have yourself sucked up and rained and fell on a bear while he hid from the rain. Then fall in a puddle, a Animal walked by and drank you.... Just some ideas but go from there add pics and details and your done.... Be creative.
