      This wasn’t an experiment, it was a demonstration in a live lecture – I exploded flour (see the picture on my profile). I wanted to do it twice, but was worried it would set the building’s fire alarms off!

      I think coagulating milk is the most exiting thing I done. I now do it all the time but it still amaze me to see how liquid can be transformed into semi-solids just by the addition of enzyme. It feel like magic to be able to add a bit of powder (Lactic bacteria), a bit of liquid ( Enzyme) to some milk and you get a totally different product: cheese.

      Good question, hard to answer though!

      Possibly one of the most fun things I did was trying get the outer skin off a frozen guava (a fruit about the size of an apple) so I could extract RNA from it. This involved freezing it in liquid nitrogen (which is very very very cold) and then hitting it with a hammer and collecting the bits that got chipped off. Despite wearing gauntlets and a face mask I still managed to get cut by a piece of frozen guava shrapnel!
