5 top finds from the web this week.

A compilation of some of the awesome stuff we've found on the internet over the past week.

1. A very social vending machine

Our friends over at PepsiCo are pretty cool when it comes to new media innovation. We spotted this new venture the other day; a touchscreen vending machine that lets you buy your friends (or a stranger) a drink.

2. The social buzz behind #RW11

The world was tuned in to London on Friday to watch Kate Middleton marry Prince William. The Royal Wedding (or #RW11 as it was known on Twitter) created quite a bit of noise via social media - even before the wedding had even happened.

Mashable created a nice infographic to summarize where the chatter was which you can see here.

3. Fire ants mimic Gore-Tex

In case you were wondering what the screenshot above was supposed to be showing; it's a submerged fire ant raft. Scientists in the US have recently discovered that fire ant rafts repel water by forming a tight waterproof weave similar to Gore-Tex. Awesome, huh?

4. Facebook worth $100,000,000,000?

The social networking behemoth was valued between $60-65 billion at the start of March. That was after being valued at $50bn in January.

On Saturday, the Wall Street Journal reported Facebook could now be worth almost double its last valuation - putting the technology company ahead of Amazon, Cisco Systems and Hewlett-Packard.

Are we approaching the next dot-com bubble burst?

5. (Re-)Building the bouncing bomb

There was a rather good documentary on Channel 4 earlier this week. Barnes Wallis' bouncing bomb was one of the engineering marvels during the Second World War. Unfortunately, many of Wallis' initial sketches and designs were lost in a flood in the 1960s. A Cambridge University engineer, Dr. Hugh Hunt, was followed by a film crew as he tried to recreate the famous bouncing bomb.
