Spray cans are highly condensed and if you cut one open, it will explode.
cut them open and see the contents of their stomachs then average them
Usually liquid.
i guess not, just check the contents.
cut
Aluminum. The depth of cut around the tab in the can top has to be very precisely controlled otherwise the pressurised contents could open the can prematurely. If the cut is not deep enough the user will be unable to open the can when the tab is pulled. Very clever bit of unseen engineering.
Probably not. The chemicals in spray cans are typically pretty sterile and relatively pure. It is not likely that they will carry bacteria. However, if the cut has not been cleaned and you spray it, you may be sealing the bacteria in an area that will allow it to multiply and infect the cut.
cant
Open it as far as it will come apart, then spray cooking spray on it. Push and pull until the spray is worked in and it should pop open. Mine did!
An envelope can be something that is very open, in order to look at the contents inside
put a plaster over the open cut
It used to be thought that this sealed the cut and kept disease out. Current practice is to let it heal over without doing anything. A healthy plant or tree will heal the cut better if left alone.
