True, but not that hard. I had some “dangerous experiments for kids” book back in the day and by far the most fun thing in it was aerosolizing flour with a straw to get the right mixture near your Bunsen burner for your own glorious short lived fireball.
And don't get me started on flour, not only it stores a ton of energy (50 grenades per kg) but it's also highly explosive! [1]
