Zombie Science: 1Z Alien Syllabus, Risk Assessment


General set up and Risks


Zombie General Risk Assessment and Set Up

This is a show about Genetic Engineering and Human anatomy. It uses the interest in Zombies as a 'hook' for a general audience.

There are no particularly unusual risks associated with this show. It is a combination of traditional Liquid Nitrogen and CO2 experiments but with some additional twists.

It is, however, a messier show that normal. As such additional precautions an staging are required for the handling of slip hazards. As detailed in the risk assessment, this consists of a zone, protected with a tarpaulin, in which the slip hazards are contained. Additional slip hazards are dealt with as they appear.

  • The audience should be at least 2 metres from the performance area.
  • The spillage / slip hazard  area is marked by a tarpaulin held in position by hazard tape.
  • Chairs should be positioned by the spillage area to allow volunteers to be seated putting on or removing protective suits.
  • Paper toweling should be available for spills and, for presenters and volunteers to wipe feet.
  • Presenters should be aware that some adult audiences members may become more unpredictable if they have been drinking.
  • A plan should be worked out in advance for chemical spillages.
  • The positioning of fire exits and extinguishers should be noted.
  • The stage should be kept tidy.
  • Trip hazards should be removed.

Demo 2 - Comet making


Comet making demo and risk assessment

  • Describe real comet
    • What they are made of
    • Where they come from
  • Dry ice of frozen carbon dioxide is very cold -79C. Four times colder than your freezer.
  • Some scientists call comets dirty snowballs
    • Mixture of ice and dust
    • All ingredients are found here on Earth
  • Mostly made up of water
  • Some scientist think all water in Earth comes from Comets.
  • Comets contain silicates
    •  lots here on Earth
    • Sand is a type of silicate
  • Carbon can be found in comets, soot is a kind of carbon.
  • Other volatile compounds have been detected
    • ammonia
    • formaldehyde 
  • We are made of organic compounds
  • Organic compounds are found in comets.
  • Amino acids and nucleotides have been detected in comets.
    • Amino acids are the building blocks of all living things on Earth.
  • Comets contain frozen gasses
  • We breath our more CO2 than we breathe in.
  • Comets have a nucleus and tail

Comet soup
  1. Pour water into bowl
  2. Put sand in bowl
  3. Add soot
  4. Add Worcester sauce - representing organic molecules
  5. Add ammonia
Freeze the comet 
  1. Make safety announcement 
  2. Show audience CO2
  3. Crush CO2 into powder using mallet
  4. Add to comet soup and mix
  5. Gather bag up
  6. Form ice into comet, allow gas to escape, away from face
  7. Show the head also know as nucleus 
  8. Demonstrate tail by blowing 
Set-up
