We're back! After Tom's travels to Japan and the U.S.A., the Mind Stretchers reunite to discover the joys of Fuji Rock Festival '25 and capsule hotels, debate which part of the dishwasher you'd prefer to get washed in, and learn how metal and rubber reacts to heat.

We're back! From the disruption of flu and music tours, Ben and Brendan reconnect to discuss Deane's homemade thermometer experiment, Superman and the film music of John Williams, and how rainbows work.

Brendan has props! Steve Mould's Assassin's Drink Bottle and its wandering knight cosy, Stephen Biesty's Incredible Cross-Sections, and we return to the work of Adelbert Ames Jr as Rob and Deane shrink and grow inside his strange room.

Brendan and Tom talk Mission Impossible, Deane shows us a topological treat with jumping paper clips and Rob crafts Punch-and-Judy-style papier mache puppets.

Brendan goes north by north-north at the Edinburgh Fringe Festival, we get a call from Mr Aphantasia himself to tell us how it feels, and Dr Rob makes a simple boot jack that makes de-booting so simple.

We did our homework about the Magic Potato Trick from last episode, and try to crack (or smoosh?) the puzzling question about which part of a ship travels furthest on a trip around the Earth.

A magic trick with a potato, a knife, and a newspaper, gives more than enough food for thought - and a menu full of wireless transmission and cutting down into the quantum realm.

An outdoor examination of insects by Rob leads to discussion of shrinking, and Deane's magic trick involving Möbius strips unravels into the world of acoustics.
