On the weekend of 6th & 7th November the LHC beam was injected and arrived near the CMS experiment, before being "stopped" by a large amount of material known as a "collimator".

A majority of the sub-detectors were operational so saw these so-called "splash" events.

You can recall the excitement of the weekend in three ways:
