An Australian company is offering people the chance to come back from the dead.
Southern Cyronics have set up the country's first cyrogenic freezer facility in New South Wales that will hold corpses until it is scientifically possible to revive them.
Participants will have to pay $150,000 to be encased in liquid nitrogen at temperatures close to -200C in steel chambers.
The bodies will be submerged feet up so the brain has the best chance of survival in the event of a possible leak in the chamber.
The company already has 40 spaces and are planning to add 600 more spots with additional warehouses. It insists that participants could be revived once certain medical advancements are made in the future.
However, the claims have been disputed by some scientists who claim that the freezing process alone is a death sentence.
Shannon Tessier - a cyrobiologist at the Massachusetts General Hospital - said: "There is absolutely no current way, no proven scientific way, to actually freeze a whole human down to that temperature without completely destroying - and I mean obliterating - the tissue."
