More questions beginning with the word How. There's a red carpet event in the HOW Hub as Sam Homewood shows how to have a solo cinema experience, Vick Hope explains how you can drink dinosaur wee, and things get hairy as Frankie Vu demonstrates how to survive a massive shock in a stunt that should never be tried at home - as always, Head of HOW Fred Dinenage is on hand, and this time he challenges the team to make perfect portraits that look pretty sweet.

Join the team in the HOW Hub as Vick shows how cream can catch you out, Frankie discovers how salt can destroy a tank, Sam explains just how you can eat a mouldy sandwich, and Head of HOW Fred Dinenage asks the team how it's possible to sculpt sand.
