Why it helps

This activity turns a simple physics concept into a motor skills challenge. Your child will learn to grade the force of their movements. By swinging a weighted cup at targets, they develop steady control. It encourages them to use both hands together for setup. This also builds focus and patience as they aim. It is a great way to practice timing and spatial awareness at home.

Steps

Tape one end of the string to the top of a doorway.
Use the hole puncher to make two holes in the paper cup.
Tie the other end of the string through the holes to hang the cup.
Place five buttons inside the cup to give it a little weight.
Set up three cardboard strips as pins on the floor nearby.
Pull the cup back and release it to knock the pins down.
Try to keep the buttons inside the cup during the swing!

Safety tip: Ensure the doorway is clear of traffic and the string is not left unattended to prevent tripping.

Make it easier

Fold the cardboard pins into tents so they stand on their own, and set them close together.
Leave the buttons out so your child can swing without worrying about spills.
Line the pins up right in the cup's path so a straight release knocks them down.

Make it harder

Set the pins up in a triangle, like bowling, and count how many fall with each swing.
Call out which pin to knock down, and ask your child to hit only that one.
Release the cup from a spot you point to, off to the left or right, so it swings at an angle.

What to watch for

Notice whether your child pulls the cup back a little or a lot, and whether they change that after seeing what happens.
Watch whether your child lets the cup go smoothly or pushes it forward. A push often makes the buttons spill.
If the clatter of buttons in the cup bothers your child, use a rolled-up sock for weight instead.
