Two hydrogen atoms, collectively known as H2, have made history as the lightest climbers to summit Mount Everest. H2’s feat was particularly impressive as they reached the peak without the aid of oxygen.
“We previously tried the climb with oxygen” said H2. “But we had barely climbed a metre when we just trickled back to the start and formed a small puddle. We soon had a severe case of frostbite and by nightfall had frozen solid.”
