We attended the Big Bang over the full 4 days of the event in 2019. Birmingham NEC was the venue and it was a great experience. This year we split the team into 2 teams one for the set-up and the first 2 days and then the other team for the final 2 days and the takedown. Much better experience for the event to not do the full 4 days in a row which was exhausting from previous experience in 2017.
Ove the course of the 3 days we spoke to and gave tokens to 3055 people which was a hell of an achievement. massive thanks to Swansea uni who gave us some money to cover travel and accommodations as well as a couple of student ambassadors to chat to people about engineering degrees at Swansea.
The individual statistics for the days are shown below shows just how much of a fantastic time we had.. The combined statistics are shown here to give a flavour of the event in total.
As you can see we had 3055 conversations with again as expected an overwhelmingly positive skew to the data. The vast majority of respondents did not have a prior opinion of hydrogen and therefore received a yellow token. This is not surprising given the nature of the event however there were lots of older students coming to the end of their A-levels who would have had a pretty good idea about hydrogen and it's possibilities both positive and negative.
Day 4 was very much the family day so there was a shift in audience perceptions. The proportion of the respondents who were adults and had an opinion was higher as seen from the greater proportion of red and green tokens on this day.
