for some unknown reason this "science is cool" dweeb tried to find the most complicated way to inflate a tire. He succeeded in proving that with 10 2 liter bottles, a garden hose, and a lot of fittings, air lines, and many hours to make this set up, you CAN fill a tire with air, using a garden hose to pressurize everything

his kids must be depressed, he probably tries this nonsense on them with every "life lesson" he tries to teach them in the most complicated "science is cool" way possible

in his own words at 4:50, he spent weeks designing and fabricating. He could have built a better air pump instead, with his machine shop.
