Overnight Sleepovers



Due to operational reasons we can no longer offer sleepovers until further notice, however we are developing a sleepover programme at the Royal Navy Submarine museum from January 2017.

For further details please email daniel.ball@nmrn.org.uk

3A Sleepover in the Grand Magazine at Explosion: Museum of Naval Firepower is a thrilling experience for any young person and, combined with an evening of activities themed on the Museum’s fantastic collection, it becomes truly unforgettable. 

Sleepover experiences cost £25 per young person (Includes activity sessions, materials and breakfast). Leaders are free at ratios appropriate for age groups. Minimum party size: 50 young people.

Our sleepover experiences are planned in partnership with the leaders of the booking group. Typically, the young people arrive at 6pm and take part in a health and safety briefing before embarking on a rotation of activities. The evening culminates with a film showing (included in the price) before bedding down in the Grand Magazine. Children and Leaders are all advised to bring a sleeping mat, pillow and sleeping bag etc. These are not provided by the Museum.

For further information, available dates and to book please contact us.

08.30am – 08.45am young people are picked up ready to leave from the museum lawn if nice weather, if wet this will be from the conference room directly opposite the main museum building.


Group leaders and adults who sleepover with groups will be told and reminded that they need to leave the Grand Magazine as they found it, they will be provided with:
· Broom
· Dustpan and brush
· Black bin bags
On the following morning after the sleepover whilst the young people and group leaders are packing away kit they must return the space to the condition which they found it.

Sleepover departure:
On the following morning the group once they have packed away kit and equipment, had breakfast and dressed they will need to move their bags etc to the main reception area.

Groups will be reminded that they need to leave the museum by 08.45am at the very latest as we will need to set up for visitors etc for reopening to the general public at 10am. If this is later i.e. towards 0900 then they will need to move over the conference room.

Wet weather plan:
Once all bags have been moved to shop and reception the whole group will then move to the conference room by entering the admin block through the back door. Parents can then collect their children from this point if wet weather.

Dry weather plan:
All young people and adults will then once bags have been moved to reception and shop will be then instructed to move outside the main buildings to be collected by the exit to be collected by parents / guardians / carers . this can also act as a photo opportunity for the whole group.

This will allow for the entire museum galleries (including the grand magazine, toilets and café spaces) to be cleared of people and those areas needed to be cleaned.


Sample Activities for Beavers/ Cubs/ Scouts Communicator Activity Badge Sleepover. All sessions will be led by members of NMRN staff and will guide groups to their next activity.


4Semaphore & Signal Flags

Find out about Semaphore signalling, create your own flags to send messages to each other. Then get to grips with the International Code of Signal Flags and try writing your name and short messages in signal flags.

Invisible Inks

Discuss why invisible inks may be useful and try out 3 types of invisible communication. Mix your own invisible ink and write a short message. Experiment with UV lights to look at luminescent dyes and solve the puzzle of how to read a note that is no longer there. Finally, develop your first invisible ink message with a secret ingredient.

Gallery Spy Trail

It is a Friday in October 1941 and a spy has been stealing secrets from the Priddys Hard Armament Depot! Work in small teams to hunt for clues, search lockers, check finger prints, interrogate a suspect (gently) and check the all-important paperwork. This begins with a short briefing from Mi5 at reception, then make your way around 5 evidence scenes, working through your spy trail notebooks. Once the activities have finished, your team will have time to discuss your solution and present your reasoning to whole group. 

Morse Code Machine Making (shown in image above)

Find out why Morse code has always been such an important communication skill. Make your own Morse code machines to try out and take home, using a simple lamp circuit and a clothes peg.


Multi- Museum Packages

Why not combine your group’s sleepover with a visit to either the Royal Navy Submarine Museum, the National Museum of the Royal Navy (Portsmouth) & HMS Victory or The Royal Marines Museum before or after your visit to Explosion.
