The night was still. Not a breath of wind could be felt. An eerie silence filled the warm evening air, broken only by the sound of the crow’s wings flapping as it returned to its nest with food.
Combined with the ghostly silhouette of the tower and the rickety pathway that led to it, the ominous silence made Lucy nervous. She felt a prickle on the back of her neck as she thought about what she might find inside the tower, and what might be lurking in the darkness around her.
Her heart began to thump inside her chest, seemingly matching the beat of the crow’s wings.
Lucy had always been slightly wary of crows; they had sooty, black wings, piercingly sharp beaks and menacing, staring eyes. The crow had settled down in one of the gnarled branches of a nearby tree. She thought it was watching her. Surely it wasn’t though? Crows didn’t do that. It must have been her imagination.
Plucking up all of her courage, she approached the stairs. They looked rotten and crumbling, as if nobody had set foot on them for years and years. The crow was still staring at her, and had tilted its head to one side as if pointing its beak towards the tower. “What was this crow up to?” she thought to herself.
“Are you trying to warn me about something?” she asked the crow. The crow did not respond, only shuffling its feet slightly on the branch, head still tilted to one side. She frowned. “Of course you’re not trying to warn me about something, you’re just a stupid bird.”
Her eyes left the crow and she ascended the first few steps on the rickety path towards the tower. “It’s just a silly bird.” Lucy muttered to herself under her breath. “Don’t be such a wimp.”
The crow watched as she left, and smiled. A wicked, cruel smile accompanied by a cackling laugh. “Silly, silly girl” it squawked. “I must tell the others she is coming.”
The crow took off into the night…

Science - DO try this at home!
This week we are going to be trying out some fun science activities. Each of these will have a short demonstration video and step-by-step instructions. If you like, you can send it a photo or video of you doing the activity!
Before setting up this demonstration it’s important to know that it only works if you’re looking at it from the right place. Either set up a chair for your family member, or if you’re doing it online position the camera on your laptop or phone, so you know where the demo will be viewed from. Now you’re ready to get started.
Optical illusions are images or pictures where we “see” something that is confusing to our brains or different to the way it really is, just like our reversing arrow.
Without the glass of water, we see both arrows as they are, pointing left to right. You can imagine light spreading out from the tip of the arrow, travelling in straight lines called rays. Some of the rays reach your eyes, that’s how your brain sees where the tip of the arrow is:
However, when we add our glass of water it gets a bit more complicated. Instead of spreading out in straight lines, the light changes direction both when it enters and leaves the glass of water. This change of direction is called refraction and it happens because the light slows down as it enters the glass and speeds up again as it leaves.
To work out the way every light ray turns when it hits the round glass, you can imagine each ray as a car driving from the road onto something more difficult like sand. As the car moves from the road to the sand it will slow down. As one of the front wheels hits the sand before the other, that wheel will slow down first and the whole car will turn towards that wheel. The opposite thing happens as the car leaves the sand and speeds up, the car will turn away from the wheel that hits the road first. The path the light takes changes in a similar way.
We can sketch out the path that some of the rays take as they travel from the paper, through the glass of water and out the other side:
Our optical illusion is that our round glass of water ends up changing the path of the rays of light enough for them to cross over and spread back out. Now, for the web cam or anyone looking at it, it looks like the rays of light are spreading out from an arrow pointing right to left instead. So we are tricked into seeing the tip of the arrow in a different place.
Investigate together with your family. Discover how what you see changes if:
To make yourself part of the experiment, sit somewhere different to look at the illusion from a different place.
Once you’ve worked out what happens with something simple like an arrow, you can try out different shapes, letters and pictures to see what happens! Can you predict how they will change when you look at them through your water?
Lots of different optical illusions are caused by refraction, from mirages in the desert to swimming pools looking shallower than they really are.
