Drac has just been copied in to the following high priority health warning from the East Midlands Ambulance Service
Jequirity Bean Bracelets that have been on sale at the Eden Project and other retailers (they look like red and black bean bracelets) are made of a deadly plant seed that is a controlled substance under the Terrorism Act in the UK and lethal if injested!
If you have one you are recommended to bag it then wash hands. (Apparently you can apply for a refund...)
