  • Funnel
  • Balloon

  • Thursday
  • 23rd March

Technicraft!
Today at science it was another day but an extraordinary experiment I had a brilliant day comparing it to last week we had baking soda 30mls vinegar 150mls we had a bottle a balloon and a funnel. Miss Gawith showed us the first of what we had to do and instructed us the first step for what we need to do she poured in 150mls of vinegar than but the funnel over the balloon and started to pour in that 30mls of baking soda into the balloon once that was done.


She placed the balloon over the bottle with 150mls of vinegar in it and uplifted the balloon above the bottle and all the baking soda gently brushed through the bottle and straight away it fizzed up until it would reach certain filling and would pop.
We were waiting for a final warning to move away from the bottle exploding in our faces and eventually it did. Half of us was a least covered in vinegar and totally it stunk the whole room and most of me being covered all in it as well.


It was then time for the groups to do this experiment and everyone was instructed to go outside because then the room will smell like vinegar  so Xyril and I found a place to do this experiment and it was a blue bench our experiment did not really turn out best because it never exploded it only fizzed up and then the balloon began to sag..



I had really enjoyed doing this experiment and I would really enjoy doing another one exactly like this but different ingredients.

Last day of technicraft

materials
  • Meths burner
  • Matches
  • Tripod
  • Gauze mat
  • Thermometer
  • Milk
  • White vinegar

materials


  1. Wipe your meths burner so that it is clean
  2. Place your meths burner under the tripod
  3. Then take the lid of the meths burner and light the meths burner with matches
  4. You will then have a measuring cup of milk and place it on the tripod.
  5. Put a thermometer in the whey, it needs to be 37°c
  6. Take it out when it reaches this temperature.
  7. Pour it over the single cup - (then the curds will stay on the top of the cup)
  8. Test your 'babyspit' to see whether it is a curd or a whey
