taken out three kilos of sand should do the trick

and after it cleans the visibility still

and after it cleans the visibility still has to be 75% the inner shell is made of

has to be 75% the inner shell is made of

has to be 75% the inner shell is made of polystyrene with three kinds of

polystyrene with three kinds of

polystyrene with three kinds of densities the reason is because of the

densities the reason is because of the

densities the reason is because of the fact that the human skull is on the top

fact that the human skull is on the top

fact that the human skull is on the top it’s quite thin and on the front side

it’s quite thin and on the front side

it’s quite thin and on the front side it’s quite hard actually so you can have

it’s quite hard actually so you can have

it’s quite hard actually so you can have a different impact on the front side of

a different impact on the front side of

a different impact on the front side of the helmet or on top of the helmet the

the helmet or on top of the helmet the

the helmet or on top of the helmet the inner shell acts like a cushion to

inner shell acts like a cushion to

inner shell acts like a cushion to absorb impact energy polystyrene beads

absorb impact energy polystyrene beads

absorb impact energy polystyrene beads are compressed

are compressed

are compressed one by one extending the time of impact

to test it you drop it headfirst sensors

to test it you drop it headfirst sensors in the 5 kilo head form measure its

in the 5 kilo head form measure its

in the 5 kilo head form measure its acceleration when it strikes the inner

acceleration when it strikes the inner

acceleration when it strikes the inner shell is there to slow the impact so the

shell is there to slow the impact so the

shell is there to slow the impact so the lower the acceleration the better the

lower the acceleration the better the

lower the acceleration the better the shock absorption of the helmets and the

shock absorption of the helmets and the

shock absorption of the helmets and the test doesn’t even damage the surface
