I think I have a pair of disposable gloves somewhere, and maybe could manage to get several glass jars, but I have no idea what the aluminium foil is for, or how to preserve the samples with it.

If this had happened to me, I would probably use Ziplock bags in the best scenario.

I'm told aluminum foil is pretty close to intrinsically sterile, at least fresh. The process of forming it kills all life and it's not hospitable to new colonizers.

The aluminium foil forms a Faraday cage that prevents the tiny meteorite aliens from calling home for rescue.
