Question: is it possible to expload things so they errupt bigger than a car?

Absolutely. There’s no theoretical upper limit to the size of explosions (as far as we know). If you’re curious about size, you’ll be interested to hear the largest ever man made explosion was the Russian thermonuclear “Tsar Bomba”. It was tested in the arctic in 1961 and completely obliterated everything within 35 Kilometres. Nuclear weapons are terrifying things, but the history of their development is very interesting.
