Answers:    call your nearest zoo they will put you surrounded by touch with the appropriate expert to relief identify the spider to find out if it's harmful, probability are if it's that colourful it's natures opening of saying I'm poisonous so monitor out! play safe and kept it surrounded by a jar for now.
seize a fly then throw it surrounded by the jar, then if the fly get killed, put a catterpillar later eventually a dog or something, until the spider is dead, or until the dog starts firing out spider web.
