This is to make measurements on the helium that we use.

What we have used:

Working out how much we need:

Using the chart from[]=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.
