Choose a good cause and come up with an original action to collect money for it.
We chose the organization 'Toverblokjes VZW', which helps underprivileged children using Lego bricks. That's how we came up with the idea to get sponsored to walk on Lego. 1 euro was equal to 10 cm. Our action was featured in the media several times and we were asked to be on the radio.
We campaigned for our action via posters, flyers and an Instagram. We let other people try it for themselves in exchange for a donation.
