But don't just take my word for it - have a look at the launching pads for tyres our kids have been creating:
And then added that extra bit of height using the slide to really allow the tyres to pick up speed:

The best part about this play? They didn't need us teachers at all.
It blows my mind what three and four year olds can achieve - on their own - when they have the time and opportunity to become fluent in the materials at hand.
The open-ended nature of loose materials in the playground provide endless possibilities for creating, investigating, experimenting, persisting and problem solving as children work together to make their own play space - and then take it all apart and start again.
And again, don't take my word for it. Have a look at the amazing play spaces created by very young children in preschools around the globe using loose materials:
