Hi my favourite scientists!
I’m back with a question for you. As we know, light can travel but, what about sound? Can it travel? How?.
Watch the video and discover the answer.
And can you guess what is this? Can you believe it is a telephone? At the end of the video you will find the instructions to build one. You can try at home and check if it works!
So good for telling your secrets in the distance! 🤫
Have fun!
