Thank you Lada and Lorrae, We are doing the experiment tomorrow, so the teacher is going to wash everything in bleach before it comes back to me. Had a quick look in my chemicals catalogues and couldn't see amalyse, any hints on where to source it? I intend to have a fantastic holiday. My dear husba...

I have a request for a prac using saliva but was told it should not be used because of the risk of Hepatitis. Would this be a written directive, if so any idea where it would come from.

Hope you all enjoyed the St Mary's confrence as much as I did. Hats off to the fab team of organisers.

We also have gamma (Cobalt 60), alpha (Americium 241, radium 226) and beta (cesium 137).

Have a nice rest of the day.

As Elodia has now been classed as a noxious weed, I am unable to purchase it. Does anyone have a suggestion as to a good replacement for Microscope lessons.

Thank you Bob,

Cheers Rhonda W

It is encased in clear perspex, has a VOLTAGE-OFF switch on the top left hand side and the Detector head is on the front. It...

I have to make 8 litres of Bubble mix. Hopfully we will be able to trap a student in a bubble. I would like to know what the best ratio of detergent to glycerine is for this and how much water should be added.
