    Those old lawnmowers were hard enough for me to push around without spikes in the wheels. The added friction of those spikes penetrating and then pulling out of the ground would have made lawn mowing a much harder chore than it was. Obviously the guy with the idea must never have tried it.

    Luminous smoke?

    Sounds like a type of firework to me.

    I.E., flares.

    Might not be bad to have those spikes. Mine always slipped on grass that was the slightest bit damp.

    Re: spikes for the mower – I read somewhere, and actually tried, wearing golf shoes to aerate the soil while mowing and doing yard work. I have no idea if it worked, but it seemed like a good idea at the time

    Hirudinea , there are vents at the top… but those could be there to hear the child scream.

    As for fruits, there are is some sort of indicator chemical which changes color in the presence of Ethan gas, which some ripe fruit emits. A small card with the chemical printed on it is packaged with some fruit.
