and cars would fly into space. We4had/'d have to fix
everything to the ground with strong chains.

People wouldn't stay on the ground either. We floated /
'dfloat around with everything else. And if people and big
objects6floated/would float around together, imagine how
many accidents 'happened/would happen!

Finally, remember that without gravity, all the water in lakes,
