2. Having a Eureka! moment in Halifax
As you approach Eureka!, the only purpose-built children's discovery centre in the UK, the echoes of The Wizard of Oz are unmistakable. You follow the yellow brick road and leave behind Kansas-monochrome Halifax for the vivid colours of Oz. Once inside, it's all primary colours. The kids are primary, too - Eureka! is designed specifically for children up to the age of 11.
As you enter, to the right Archimedes waits to be dunked in his bath. Our Global Garden provides an early highlight, ranging across six world environments, from the jungle to the arctic. At either end, toddlers' sections encourage under-5s to roam and explore.
In Living & Working Together, a role-play area teaches older kids how to get to grips with grown-up life. In the bank (Halifax of course) they can take cash out of an ATM, sit on a chair made of a million pounds (not, alas, real notes) and dodge the alarms in the bank vaults.
A hundred other hands-on activities crowd the M&S shop, a post office, and a garage. Everything - phone box, lift, front door - is used to elucidate and explain and educate.
3. Falling into Oblivion at Alton Towers Theme Park
Imagine yourself as an astronaut during the launch: facing upwards, strapped into a fire-breathing space shuttle, with 3Gs of force squeezing down on every fibre of your body. You'd probably be terrified. Reverse this situation so you're facing downwards, and then pile on another 1.5Gs of force, and you're some way to describing how it feels to ride Oblivion, the world's first vertical roller coaster, at Alton Towers.
Admittedly, the ride can't compete with a space shuttle's 17,500mph top speed. But you don't need any training to enjoy it. All you have to do is join the queue and begin preparing yourself for a 150ft drop into a steaming black hole. Eyes open or eyes closed, that drop feels incredible. For the first second or two of carefree euphoria, you'll surge straight down towards the earth.
Then you'll tunnel below the surface on a terrifyingly gloomy section of track, before emerging into the daylight for a 190-degree banked turn that makes your skin rumble with delight. Right then, even without a space shuttle, you'll feel like a hero.
