We bought 1 pack of this stuff at the Kaufhof, paid 10 euros for it proud. On the one hand: Just like the other buyers, I find that the information on the packaging or in advertising are misleading. 30 liters of water is very very little to "have fun". You might be enough for a 1.5-2 J. old child, but not for 7-8-year-old kids. Si as the other have the Glibbistückchen distributed with us everywhere :-( Dissolving v. Glibbi did not go in! We have done everything according to instructions while the porridge was still there, where even after 15 minutes saline to further 10-15 minutes gewartet- nothing! So I was able to get a bucket, an old kitchen sieve (approximately 12 cm in diameter, this statement only because of the dimensions) out shoveling and all that crap so from 60 liters of water. After 30-40 minutes in an extremely uncomfortable position I rausgeholt proud 10 liters of it. The rest I run down the drain, a few buckets of clean water afterwards, so that the outflow is not blocked ... The result: fun had my 8-year-old son does not necessarily, after less than 10 minutes he wanted to get out. I am glad that we have not used both bags at a time, otherwise the action would have taken with the rid of this crap any longer and the back pain would be worse. I am now trying to get my money from the manufacturer or the distributor of this Sch .. get back.
