Have you had the top of your head sawn off and polystyrene foam pumped into the cavity?

One clip captures the moment he flew through a polystyrene foam target measuring 30cm by 30cm held 1.5 metres above the ground, setting another world record in the process.

Molded green polystyrene foam trees along with vacuformed shrubs and vines also provided some crude landscaping.

Behind these tubes are bundles of closed-cell polystyrene foam, placed between the barrier and wall.

Any other flame retardant would likely need higher load levels in the polystyrene foam.
