The Möbius strip has fascinated scientists and mathematicians since its discovery in 1858. It’s a one-sided, non-orientable surface that can be made by twisting two ends of a strip of paper. A Möbius strip can be any band with an odd number of half twists, meaning it has one edge. It’s very easy to make…

In this science activity, you can put a balloon into a candle flame without it popping! How is that possible? It’s all about heat transfer. A balloon filled with air will pop when it gets too close to a flame as the heat from the candle warms the balloon’s skin and weakens it. The trick…
The Moon doesn’t make its own light. We see it because light from the Sun reflects off the lunar surface, but why does the Moon look white? If you could actually stand on the Moon, it would look mostly grey with areas of brown and yellow, depending on the minerals present. The Moon appears white…
