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
