Find a plastic bag (carrier bag or small bin liner) and a length of string about 1 metre long.
Tie the string firmly to the bag handles or one corner.
Hold the string and run — show your child how the bag lifts and flies behind you.
Hand the string to your child and let them run with it.
Encourage them to try different speeds: 'Run fast! Now slow down — what happens?'
Stand still and feel the wind pull the bag: 'The wind is doing the running now!'
Try different directions — running with the wind, against the wind, across it.
When energy is spent, let the bag go (pick it up after!) and watch it fly away briefly.
Parent tip
Set out plastic bottles and string or yarn before inviting your toddler in so the first minute feels smooth.
What success looks like
Flushed cheeks, big smiles, and a calmer child afterwards. If they want to do it again, you’ve found a winner.
A carrier bag or bin bag tied to a length of string becomes a kite that flies behind your child as they run. On a breezy day, they discover the relationship between wind, speed, and lift — running faster makes it fly higher, stopping makes it drop. Pure physics joy, zero cost.
Why it helps
Running with resistance (the drag of the bag) builds cardiovascular fitness and leg strength. The WHO recommends children under five get at least 180 minutes of physical activity daily, including energetic play. This activity also introduces cause-and-effect reasoning — children experiment with how speed and wind direction change the bag's behaviour.
Variations
Decorate the bag with stickers or markers before flying it — turns it into a personalised kite.
Attach ribbons or streamers to the bag for a more dramatic tail effect.
On a very windy day, try standing still and holding the string tight — can the wind hold the bag up without running?
Safety tips
Use string no longer than 1 metre to prevent tangling around the child's neck — never use long strings unsupervised.
Choose an open space away from roads, trees, and overhead wires.
Pick up the bag afterwards — do not leave plastic in the environment.
