🍫 The Mystery of the Shrinking Euro
One Snickers bar. Two prices. Seven cards. The whole team helps you crack the mystery of why money quietly shrinks over time — and what grown-ups do about it.
“In 2015, a Snickers cost €1. In 2026, the same Snickers costs €1.20. The chocolate didn't change. So something else did. Let's investigate.” — Goldie

🔍 The mystery
Last year a Snickers cost €1. This year the same Snickers costs €1.20. The chocolate is exactly the same. So what actually changed?
📖 The real rule
Inflation is the slow rise in prices over time. The same money buys you a little less each year. It's not the products getting fancier — it's the money getting quietly weaker.
“Like a balloon slowly losing air. Same balloon — smaller inside.”— Goldie
Card 2 of 7 · Taught by Penny
🔍 The mystery
But WHY does the Snickers cost more? Did the chocolate become more chocolatey? Did the wrapper get fancier? Of course not!
📖 The real rule
Three usual reasons: (1) there's more money floating around than products to buy, (2) making the Snickers itself got more expensive — sugar, energy, transport — and (3) lots of people want Snickers right now and there aren't enough on the shelf.
“Whenever something gets more expensive, ask: who has more money — or what got harder to make?”— Penny
Card 3 of 7 · Taught by Cash
🔍 The mystery
Your money jar has €10 in it. You leave it there for 10 years. The jar still says '€10'. But what can it actually buy?
📖 The real rule
Money sitting still in a jar (or a very low-interest savings account) slowly loses what it can buy. €10 today might only buy what €7 buys after ten years of normal inflation.
“A coin that doesn't move forward is moving backward — even if it sits very still.”— Cash

🔍 The mystery
If money loses value sitting still, what do grown-ups do about it?
📖 The real rule
Many adults invest part of their long-term savings in things that historically grow faster than inflation — like shares of many companies bundled together. Over decades, broad world stock investments have beaten inflation in almost every long stretch.
“Beating inflation isn't a race for one year — it's a marathon for thirty.”— Goldie
Card 5 of 7 · Taught by Byte
🔍 The mystery
Is some inflation OK? Is zero better? What about negative inflation? The answer is surprising.
📖 The real rule
Most central banks aim for about 2-3% inflation per year. Too high (above 10%) and prices feel out of control. Too low or negative (called deflation) and people stop spending — which can hurt the whole economy.
“The sweet spot is a slow, predictable rise. Boring is the goal in money.”— Byte
Card 6 of 7 · Taught by Tally
🔍 The mystery
Has inflation ever gone REALLY wrong in history? Yes — and the stories are wild.
📖 The real rule
In Germany in 1923, a loaf of bread cost a wheelbarrow full of cash. In Zimbabwe in 2008, the country printed trillion-dollar bills. When governments print way too much money to pay their bills, inflation can explode into 'hyperinflation' — which destroys trust in the money itself.
“When you read history's hyperinflations, normal 2-3% feels like a gift.”— Tally
Card 7 of 7 · Taught by Cash
🔍 The mystery
Knowing inflation exists is one thing. What does a normal family DO about it?
📖 The real rule
Three habits help: (1) keep emergency cash safe but not too big, (2) long-term savings → consider investments that historically beat inflation, (3) watch the prices that matter to YOU — groceries, energy, school costs — not just the headline number on the news.
“Don't fight inflation. Outpace it — calmly, over many years.”— Cash
🎓 Mystery solved
Inflation doesn't shout. It whispers — in every receipt, every price tag, every news headline. Now you know what to listen for.
