 +What we have used: 
 +[[https://​www.gas-uk.co.uk/​helium-10-litre.html]]
 +
 +Working out how much we need:
 +
 +Using the chart from [[https://​ukhas.org.uk/​guides:​balloon_data?​s[]=helium]] we've calculated using a 1000 totex balloon that we need 2.23 cu. m for a 500g payload. This translates to 3 litres of liquid helium. We would buy the 10 litre bottle from Gas-Uk, which **should** be enough for three flights.
