Stick em up

For his birthday L got 2 nerf guns that shoot rounds of foam bullets, needless to say you have to keep ducking as bullets go flying round the house. And they hurt!

The smaller gun has suction cups on the end of its bullets so the latest game is M shooting and sticking them to the windows . The velux ones are his favourite as poor L cant reach to get them back down. However, L has discovered he can shoot them free with his other gun. Do you think my windows will survive?
