You thought camera couldn’t be fun; then try this one, the Holga K202 Cat Camera. This camera is made to attract and keep kids focus on looking at the camera with its meowwwww sound.
I know first hand taking pictures of kids can be really hard when they are not interested, but I’m not really sure sound effect like cat calls would be effective.
If you do think it will work effectively in term of capturing kids attention, then you can buy one on Ebay for $29.99 (buy it now).
