Please note: Some experiments of the Science Kit “Heat” use an unshielded flame or
an immersion heater as heating source. Therefore all experiments have
to be accomplished with a maximum of accuracy and cautiousness to
prevent accidents like burns or scalds.
Heated elements must cool down before being restored in the kit.
