I call it Piles of Pipe Cleaner Fun.
It was essentially getting a bag of pipe cleaners in my bag was 100 (hence the piles) which I picked up at a dollar store and then used various shaped bottles.
The aim of the game was to pick up pipe cleaners and fill the bottles up with them - while of course they were exploring all the other wonderful things about pipe cleaners.
For the children it is a fantastic activity for fine motor skill development, concentration and they were fascinated by the colors, textures and bendy shapes they could make with the humble pipe cleaner.
The activity is inexpensive as you already have the bottles lying around home and the pipe cleaners are only a $1 if you search.
The age range is probably 1 year old to 2.5 year old would enjoy the fun
Would love to hear how your children find it if you try this idea out.
Happy Play Times :-)
