This is another quick way to impress your five year old. Actually, it wasn't all that quick, but not too time consuming overall.
And it looks so cool!
It's a spiderweb, in case you can't tell.
It's not perfectly formed but when your 2 and 5 year olds are helping you out at every step along the way, you've just gotta go with the flow and give up that hope for perfection.
Here's what you do:
Cover a bowl in tinfoil.
(I blu-tacked the foil in place)
Lightly grease the foil.
(I used olive oil and a pastry brush)
Lay out string or wool in the shape you desire, on top of the foil.
Get your hot glue gun into action and cover the strands of string in hot glue.
Go over it at least a couple of times.
Remove creation from bowl.
(I cannot claim this idea as my own, we came across it somewhere on the web while searching for other Spiderman related things.)
I'm on a glue gun kick now, must see what other projects I can apply it to...
