To climb the Eiffel Tower, you have to spend energy that can be fed to your body through food, so how many rubber bears do you have to eat to compensate for the energy needed to climb the Eiffel Tower?
Note: Unknown sizes should be checked on their own.

Solution:

Various sizes must be checked or estimated:
Height of the Eiffel Tower: 300 meters
Energy content of rubber bears, 100 grams, 1472 kJ. Assuming that the body can convert 3/4 of the energy, are available approximately 3/4·1472 = 1104 kJ
Mass person (z.B. Professor of chemistry) 75 kg

1. Energy required to lift 75 kg to 300 m
       E_pot = m·g·h = 75kg · 10m/s² · 300m = 225'000 J = 225 kJ
2. about 1104/225 = 5 · run up the Eiffel Tower or about 1/5 of the pack (20 grams) to climb the Eiffel Tower once
