Hypnotic Jellyfish Aquarium
Help them drift into 40 with a gift that they won’t be able to take their eyes off. Soothing to watch, it’ll take their mind off their inevitable old age and stop their legs going to jelly about it. We’ve been assured that it’s not actually hypnotic, but we’d check on your 40-year-old at regular intervals, just in case, or leave them to it if you’re enjoying the peace and quiet.
