The internet is educational. Honestly. You can learn just about anything online - a new language, how to play the didgeridoo, the best way to carve a wooden fish (we stumbled upon that last one quite by accident).

But Web Watcher is not about assigning you homework. We want to enrich your life in more shallow ways than learning French or a life skill ever could. So, we've dug up some instructional videos bound to make you either the envy of your peers or, if you're a bit more advanced in years, inappropriately and embarrassingly “street” for your age.

Let's begin with a lesson in dancing the robot. Visit tinyurl.com/6xucqs for your step-by-step guide to removing all human characteristics from your dance moves. Lesson one: learning how to “dime stop” and bounce. All going to plan, you could invest in a pair of white gloves and face paint and end up mistaken for the magnificently mechanical street performer at www.revver.com/video/18076/rocco/.

But perhaps your joints aren't what they were and your limbs no longer lithe. Then, your best bet for pulling off the robot is to invest in a video camera and use clever time-delay techniques. Copy the creative folk at tinyurl.com/5tp58u and you'll pass with flying colours.

Now let's take a trip to the beach to learn how to make a serious sand castle. If you can get past the gratuitous bikini shots, the clip at tinyurl.com/67uh55 will give you the basics of building. But for real inspiration, visit tinyurl.com/68n24r to watch a living room, complete with couch, cushions and television, being constructed entirely of sand. Still wondering what business adults have using buckets and spades (albeit fancy ones) at the beach?

Perhaps it's not so much the building as the disassembling of sand castles that you should be learning about. Check out the new trend for blowing up sand sculptures at tinyurl.com/6zw8kz.
