Population

• 2 billion children (persons under 18) in the world

• Muslim, Hindu, Jewish and Buddhist kids excluded -85% work = 378 million

• 3.5 children/ household 91.8 million homes

Time• Santa has 31 hours

thanks to time zones and the rotation of the Earth (assuming he travels east to west)

• 822.6 visits per second

• 1/1000th of a second to do everything

Distance• Stops evenly distributed • 126 km/household• Total of 121.5 million km

Nutrition• Every family

1 cookie + 2.5 dl 2% milk• 225 calories

(cookie=100, milk=125 )• Nr of calories/house × nr

of homes (225 × 91.8 × 1000000=20,665,000,000)

• 1 kg = 7700 calories• Nr of calories / nr of

calories in 1 kg = Santa gains 2683,7 tons

Payload on the sleigh• Each child- 1 medium-

sized lego set• 321,300 tons not

counting Santa• Average reindeer can

pull circa 140 kg. • Statement: „flying

reindeer” can 10 times more

• We need 214,200 reindeer

• Total payload: 353,430 tons (4x Queen Elisabeth)

Velocity• 1046 km / second

3,000 times the speed of sound

• Ulysses space probe (fastest manmade vehicle): 45 km/second

• An average reindeer can run 24 km/ hour, tops.

Result• 353,000 tons

travelling at a 1000 km/s speed enormous air resistence

• Heat the reindeer up• The lead pair of

reindeer will absorb 14.3 QUINTILLION joules of energy. Per second. Each.

• Deafening sonic bombs

Result• Santa subjected to

centrifugal forces about 17,000 times bigger than gravity pinned to the back of his sleigh by around 1 950 000 kgs of force

• The entire team will be vaporized within 4,26 thousandth of a second
