AIBU to wonder WTF is in my bag

[Mellowautumn]

On hoilday - UK cheapish but nice hotel - lying in bed listening to my swimming bag (only 3 cossies and shampoo/conditioner in ) making a weird bubbly popping sound since 2 this morning. Kids asleep in same room so dont want to open bag and scream but what the hell is in there?????? Thought it was just maybe an expanding shampoo bottle but its been going on for 4 hours !!!!

I would be terrified - how about enjoy a cup of tea and wait for DC's to wake up and investigate?

You need to open it and see.

...and then report back

Better to deal with it than spend hours awake.

Nothing !!!

No idea what it was :( was probably not in the bag but maybe the skirting board

Just the swimming stuff? Was it on the floor, could there be a gurgly pipe running underneath? Has the popping stopped - I am intrigued!
