Kids, do you remember the pendulum art in »ï¼º meuseum? you really liked it. We can do the same thing at home. It is so simple.
If you suspend an object and give it a push, it will move back and forth at a regular rate. so sometimes you can create some great art on the table
Look. I made a funnel and a paper cone to line the funnel. and tie a string around the lip of the funnel. and suspend the funnel above the table
Now, Put the paper cone into the funnel. before you pour in some salt, block the funnel¡¯s tip with a finger and remove your finger.
Push the funnel gently, and let it swing.
look!! The salt form a pattern on the table!!
It is fun!!
After the funnel stops, pour the salt back into the funnel. then you can enjoy it as many times as you want!
