How to entertain 2 10 year boys indoors

[Generallyok]

Ds has hideous hay fever at the moment and is really struggling. He has a friend home for tea tonight but obviously in the normal way they would be playing out doors or I would take them to a park. He is playing on the wii quite a bit but I am struggling to think what we can do indoors for 3 hours! Any suggestions great fully received. I thought I would let them watch a movie while eating their tea too.

I'd go with unlimited tech and screen time tbh. Must be rubbish being stuck in and it's not as if you can really do baking and crafts at their age!

I reckon you could get them making their own pizza and chips and they'd enjoy it. And perhaps ice cream factory style sundaes for pudding, plus mocktails? I have more experience with girls of this age who would love this but worth trying with boys?
