- Vícha V., Formánek P.: Heat pack, Fair 11, Olomouc 2006It is possible for some substances to stay in a liquid state at temperatures and pressures below their triple point values. Crystallization in such a state releases its internal energy in the form of heat. Simple measurements concerning this phenomenon can be conducted with a heat pack (Fire Bag)
- Vícha V.: The Propeller in Lab Exercises, Fair 8, České Budějovice 2003Three ideas for laboratory exercises (Rotation movement, Propeller and a monitor, Draw force of a propeller) and one problematic experimental task (Propeller as a balance wheel) with a simple propeller.
- Vícha V.: Utilization of a microphone for measurements in mechanics, Fair 9, Brno 2004Two laboratory exercises with a microphone connected to a sound blaster which is used for an accurate measurement of short intervals.
