KRAUL MEMORY METAL ENGINE DETAILS
A kit for young engineers 13+!
The metal wire 'remembers' a different shape when it gets hot. �� Dunking it in hot water generates kinetic energy, as this little kit impressively shows.��
Fill a suitable cup or tea glass with boiling water and fix the Memory Metal Engine to it with the clip. �� The lower pulley should dip approx 5 mm into the water. �� The heated section of the wire tries to straighten and generates a driving force. �� Flip the engine's propeller and the Memory Metal Engine starts immediately and keeps running as long as the water temperature is above 70 deg C.��
Note! Be careful with boiling water!��
Kraul products are recommended for ages 4 - 13yrs. �� Assistance may be needed for younger children... but a little bit of help goes a long way, for toys that will last for many years to come!
