Smoke flare

We did our smoke flare, which is created using a satay stick, ping-pong balls, and aluminum foil. We cut the ping-pong balls into halves, we used 6 of them and we had gotten 12 halves. next, we pierced through the halves using the satay stick, then covered it with aluminum foil completely, leaving an entrance at the top for the smoke to escape. we then burnt the smoke flare on the entrance of the smoke flare. it created a lot of smoke, however, those gas produced might be very poisonous, as, first, it came from a plastic aluminum foil, and also, it is pungent.
We showed how our smoke flare worked and the demonstration to Ms Pua, however, we did not take a video. We bought 6 boxes of ping-pong balls each containing 6 of them, however, we only used one to show, and the other 5 boxes are destroyed due to accidents.
We will try again once we gathered enough funds and remake the smoke flare, and take a video of it again. We will succeed :D
