Leaving home!

My bean has now got so big, soon I'll have to put it either outside or in a bigger pot and leave it inside. I'm getting really excited because its flowers are getting bigger. There's one problem though, it's that the roots are getting to big for the pot, so if we pull the plant by the stem the plant stem might snap, so what we thought of was if we cut the pot open down the side so it will be easier to get the plant transferred to a different pot. This morning I gave my plant 100ml of water.
