What you’ll need –
A flat section of grass or decking close to a hose (It will NEED to be level or your Blob will just roll down the hill…trust me!!)
Hair Straigtener (if you don’t own one you could follow the directions for an iron found here).
Clear plastic sheeting
Firstly I folded my plastic in half to give me a 2 x 2 meter square. I then folded a strip of baking paper in half lengthways (aprox 80cm in length). I placed the folded paper over the join at the fold of plastic.
I then clamped my heated hair straightener over the folded paper and gradually moved along the folded paper as pictured. Continue to work your way around the plastic joins until you reach the final corner, you will need to leave a 3cm hole to feed the hose into your plastic pocket.
I used my phone to time how long the above took me (nearly 19mins)– granted this was my first time I think that was fast :)
We started by adding some blue food colouring (aprox 20ml), then we inserted the hose and watched it fill. The kids enjoyed watching the blue food colouring spread.
We will definitely be doing this again and again over the summer months! How much FUN would it be at a Pool Party??!!
