Feat happens in Rollercoaster, episode 1 of Phineas and Ferb. Doof survives being hit with a ton of tin foil.
Calculation[]
Doof says he bought 80% of tinfoil in the USA.
Annual production of Tinfoil in the US was about 660,000 tons in 2003. The episode was released in 2007, so times that by five.
660,000 * 5 = 3,300,000 tons
Or 2,993,709,642 kg
2,993,709,642 - 20% = 2,394,967,713.6 kg
Doof said it was moving at 200 mph, so 89 m/s
2,394,967,713.6 * 0.5 * 89^2 = 9.4852696e+12 J
2.26 Kilotons of TNT
Edit: Danville is located in the Midwest, so the speed is obviously higher than 89 m/s
Using a rough calculated distance using South Dakota to Portland, I get a distance of 2,667,130.158 meters.
The entire event takes about 41 seconds to play out.
2,667,130.158 meters / 41 seconds = 65,051.9551 m/s
2,394,967,713.6 * 0.5 * 65,051.9551^2 = 5.0674605e+18 J
1.21 Gigatons
And since of course people are complaining about inconsistent size.
Doof is 86 pixels and the ball is 806 pixels Doof is 1.88 meters.
806 / 86 = 9.37
1.88 * 9.37 = 17.61 m
17.61 / 2 = 8.805 m
2,859.41 m^3
2,859.41 * 2700 = 7,720,407 kg
65,051.9551 * 0.5 * 65,051.9551^2 = 1.3764203e+14 J
32 Kilotons
