Watch Joe's report
A man from Sussex is hoping to get into the record books by spending nearly four months in a room with some of the world's deadliest snakes!
David Jones is flying to South Africa for the challenge which is going to begin later this month.
The current record is held by South African Martin Smit, who spent 113 days sharing a room with poisonous snakes without being bitten.
David is aiming for 121 days, to raise money for charity.
His room-mates will include deadly puff adders, snouted cobras, boomslangs, green mambas and black mambas.
