Summer holidays have well and truly started now, so a bit of a quiet week on the event calendar front. As always, if we’ve missed any out, do let us know!

One for children on holiday at the Royal Institution today: the L’Oreal Young Scientist Centre will be opened up for a workshop on making fizzing bath bombs, lip balms and more. 10:30am – 1pm, £10 a head for children 7+; book soon because it’s almost sold out.

Wednesday

Good opportunity to see behind the doors of one of London’s lesser known collections: the UCL Institute of Archaeology hosts the Festival of British Archaeology today. Activities for family all day as well as tours of the collection. 11am – 5pm.

Thursday

Imperial College and the Royal Institution team up for Urban Sputnik, an event to mark the astrophysics-meets-art exhibition of the same name.

This free talk will be held in the RI’s Time and Space bar with the creators of the exhibit. 7pm.
