Norimaki Synthesizer Taste Display: a tasty sample of science

Imagine a device which could replicate any taste. Millions of dishes, drinks, desserts and snacks and your fingertips or, more accurately, at the tip of your tongue. Introducing the Norimaki Synthesizer, a device which, using electricity, electrolytes and 5 different gels, can produce flavours directly onto your tongue. So how does it all work?

My academic lecture was part of my school’s “Academic Fortnight”, 2 weeks of short 15 minutes morning lectures before lessons by student volunteers and external speakers from Portsmouth University (our local university).

Below, I’ve attached my slides and my talking points, though I largely speak ad-lib so they’re not very long or detailed:

They work quickly and effectively: simply snap the metal plate and wait for the crystals to grow and your hands to warm.

But how does it work? A wonder of chemistry, clearly. But some keywords are saturated (well, actually supersaturated), instability, crystalisation and exothermic. You can probably piece together a rough idea of what happens, so below I’m going to go into more depth and detail!
