Please store safely, do not prank people with these. Slowly unscrew the safety lid as the gas will have built up, this alone will be enough and complete removal of the lid could be unnecessary. Hold away from the body and do not shake. Ensure the lid is on tight and stand upright. Keep out of the sun and heat where possible.
If in any doubt whatsoever, buy Kick in the D!ck instead.
