I wonder if the weight of the product it greater than the weight of the reactant.

When I was a kid, Christmas indoor fireworks used to include something like this.

Now, health and safety + the 'I will sue you' brigade have made sure that nothing like this will be enjoyed by kids any more.

Thanks davymid, one can learn interesting things here on IAB
Wikipedia says:

Tabletop volcanoes and thermal decomposition
The volcano demonstration involves igniting a pile of the salt, which initiates the following exothermic conversion:[7]
(NH4)2Cr2O7 (s) → Cr2O3 (s) + N2 (g) + 4 H2O (g) (ΔH=−429.1 ± 3 kcal/mol)

Ammonium dichromate - I'm actually proud that I remembered that, it's been a few years since chemistry class...

Link: Mini Volcano Is Cool... SCIENCE! [Rate Link] - Don't try this at home--apparently the fumes are carcinogenic.
