Exploding photographic film case

IntroductionEducational data logger

Dry ice or coolant spray is put into film case and the lid of the film case is put on. When dry ice or coolant heats up the lid blows off.

Experiment gives an application of forces.

Pupils need to know about volume changes from liquid to solid to a gas.

Target age groups — GCSE or A level, 11 to 18

Equipment required

Experiment setup

DrDAQ data logger and software

  • Connect the force sensor to the voltage and ground connections using DrDAQ’s screw terminals
  • Place the film cartridge on the force sensor and step back. A piece of Blu Tack and a penny coin can be used to give a firm base for the sensor. Blu Tack can also be used to attach the sensor to the bench.

PicoScope settings

  • Input: voltage
  • Time settings: 1 ms/div.
  • Trigger: single, volts, rising 10 mv, -2%

Carrying out the experiment

  • Put coolant/dry ice into film case
  • Push lid on hard
  • Place film case onto the force sensor and step back sharply

Questions and discussion of results

  1. What does the area under graph represent?
  2. How would making the surface softer affect the graph?


  • I have been using my 4224 PicoScope for years. I travel abroad so this has been ideal due to its physical size. Storage of waveforms on my Laptop is very easy allowing me to quickly email waveforms to my Colleagues.

  • Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. This made my decision much easier when I was looking to buy an USB scope.

  • We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations.

  • PicoLog TC-08: This is a very nice unit that works consistently and reliably.

    Jeff Hulett
  • It is a great scope. I had a weird problem - it did not work on one of my PC’s. Customer service gave me first class service. If I could give 6 stars for customer service - I would do so.

  • Perfect Partner for Development of Encoder controlled Stepper Motor Actuators. Since the included software is really stable, this type of device is a great tool for great tasks!

    Helmut Schoettner
  • A superb piece of equipment worth its weight in gold

    Nigel Clinch
  • So simple to use & beats any other I have ever used hands down.

    John D Samsing
  • Great functionality in a compact size. I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. Calibration equipment is a breeze with that feature.
