How children play with it
A child hangs an apple from the hook, the spring stretches, the pointer moves. “150 grammes,” calls out one of the children who’s just learnt to read numbers. When pulled across the table, resistance becomes visible; let go and the spring bounces back. Science starts with visible wonder, not with formula sheets.
