ESTIMATE the number of SI-Cards and win one SIAC

Do you have any idea how many SIACs we put in this vessel? Estimate the number of SIACs and write it as a comment under our facebook post. The one being closest at the real number will win one SIAC in his/her favourite colour. Have fun!

You can write your suggestions until Monday, 28th of March. The winner will be announced next week at our facebook page.
