Although this scenario is unlikely given human olfactory ability, scientists with very sensitive equipment have done essentially this with ice cores. As ice is laid down in places such as the Greenland or Antarctic ice sheets, it traps small bubbles from the atmosphere at the time within it. As long as the ice remains frozen, those bubbles remain trapped and do not interact with the current atmosphere, preserving a record of the chemical composition of the air in the past. There have been many scientific expeditions to drill ice cores and then melt pieces of them in a laboratory where special equipment can analyze the ancient air as it is released to study the quantity of oxygen and CO2 within in. The deeper the core is drilled, the farther in the past the sample. | Although this scenario is unlikely given human olfactory ability, scientists with very sensitive equipment have done essentially this with ice cores.

He is renowned for having brought science into the homes of tens of millions. The title text humorously suggests that Cueball's "narration" about what he smells in the bubble wrap is as important and distinguished as Attenborough's award winning work. |
