I love watching kids. They start pretty clueless. This one is shooting a bubble gun at his opponent. Yeah, sorry, you can barely see the bubbles. He’s standing close by because he is downwind. Get it? You need to be upwind in order really shoot bubbles. This kid was having a blast anyway. It just wasn’t an effective exchange.
The same kid and his sister had a kite each. It was neat. The father launched the kites. They stayed in the air a mere few seconds until the string got all tangled. The string was across the walkway so that unwary passersby would be caught up. That worked out really well, hence, the bubble guns. I think even that was too complicated. At least I got entertained too.
