What makes warm weather better? Especially to a kid, the answer can be a shaved ice "sno-cone" to cool the body.
If bringing the "shaved ice experience" into your home sounds cool to you, then there are machines for home kitchens that can help you do just that.
I have researched the shaved ice machines sold online -- some are electric, some are manual, all shave ice.
Here on this wizzle is what I have found.
