GUIDE

How to use?

STEP ONE

Prepare a hot cup of tea and place it on a stable, flat surface.
The tea should be freshly made and steaming — that’s the perfect temperature.

STEP TWO

Carefully set the Heatshift on top of the cup so the metal plate rests above the hot steam and surface heat.

Give it a few moments to warm up.

STEP THREE

Gently nudge the flywheel.
The engine will start spinning smoothly, powered only by the heat rising from your tea.
