    Easy to use, basic water rocket parts (just add bottle & tire pump). Enjoyed by kids and adults.
    Very fun for all ages - adults liked playing with it as much as the kids. Works great. "A good time that was had by all".Comes with- 2 rubber cork plugs- 2 sets of 3 fins (and a spare fin for each set, tho they seem pretty durable, no breaks yet)- 2 plastic air tubes to connect tire pump to rubber cork in water bottle.- 4 small plastic connectors for connecting tire pump to the rubber cork via clear plastic tube(basically, one connector thru rubber cork, connect clear tube, another connector for bike pump; 2 sets)Minimal assembly:Insert tire pump connector thru the rubber cork provided so it sticks out thru wider part of rubber cork (only goes 1 way, cant mess it up)Connect clear plastic tube to connector on rubber cork, and insert other small connector into the other end of the clear tube to connect to tire pump (basically, 1 connector for each end of clear tube).Fill water bottle 1/3 full with water.Press the rubber cork into bottom of bottle. Press HARD.The harder you press it in, the more pressure is needed to pop it out and the higher it will go.Stand rocket up on fins as its launch pad.Start pumping the bike tire pump until the cork pops out and the rocket launches.(While reading about these bottle rockets, I could never figure out what the release mechanism was to actually launch the rocket - turns out its a function of how tightly you insert the rubber cork, thats it).We were launching 200-300 feet in the air once we figured out we just need to push the rubber cork in harder.While you can use any 1 liter bottle, I prefer the Seagrams Tonic 1 liter bottle - cuz then I have an excuse to make Gin & Tonics too! However, the Polar brand Tonic bottle is more streamlined, looks more like a rocket.And you can cut the top off another bottle to attach it on top of the main engine bottle for a bigger rocket, and a more streamlined look. (pointed nose vs flat bottom of main bottle on top) Google around and you will see examples.

    Reviewed in the United States on September 9, 2022
    Very fun for all ages - adults liked playing with it as much as the kids. Works great. "A good time that was had by all".

    Comes with
    - 2 rubber cork plugs
    - 2 sets of 3 fins (and a spare fin for each set, tho they seem pretty durable, no breaks yet)
    - 2 plastic air tubes to connect tire pump to rubber cork in water bottle.
    - 4 small plastic connectors for connecting tire pump to the rubber cork via clear plastic tube
    (basically, one connector thru rubber cork, connect clear tube, another connector for bike pump; 2 sets)

    Minimal assembly:
    Insert tire pump connector thru the rubber cork provided so it sticks out thru wider part of rubber cork (only goes 1 way, cant mess it up)
    Connect clear plastic tube to connector on rubber cork, and insert other small connector into the other end of the clear tube to connect to tire pump (basically, 1 connector for each end of clear tube).

    Fill water bottle 1/3 full with water.
    Press the rubber cork into bottom of bottle. Press HARD.
    The harder you press it in, the more pressure is needed to pop it out and the higher it will go.
    Stand rocket up on fins as its launch pad.
    Start pumping the bike tire pump until the cork pops out and the rocket launches.

    (While reading about these bottle rockets, I could never figure out what the release mechanism was to actually launch the rocket - turns out its a function of how tightly you insert the rubber cork, thats it).

    We were launching 200-300 feet in the air once we figured out we just need to push the rubber cork in harder.

    While you can use any 1 liter bottle, I prefer the Seagrams Tonic 1 liter bottle - cuz then I have an excuse to make Gin & Tonics too! However, the Polar brand Tonic bottle is more streamlined, looks more like a rocket.

    And you can cut the top off another bottle to attach it on top of the main engine bottle for a bigger rocket, and a more streamlined look. (pointed nose vs flat bottom of main bottle on top) Google around and you will see examples.

    Reviewed in Italy on January 4, 2023
    Regalato a mio figlio di 9 anni che sta studiando i vulcani a scuola come approfondimento pratico su come si verifichi un’eruzione ho trovato il gioco davvero semplice ma ben congeniato.
    All’interno della scatola si trova tutto il materiale per poter costruire col gesso il modello del vulcano ed i colori per dipingerlo.
    Le istruzioni sono in inglese ma comunque molto intuitive.
    In un paio d’ore è già tutto asciutto e pronto per far vivere l’esperienza ai bambini semplicemente aggiungendo bicarbonato ed aceto nella bocca del cratere.
    Impossibile fallire!
    Peccato solo che avevamo finito tutto il rosso per la pittura e non abbiamo potuto colorare la lava rossa sarebbe stato perfetto!

    Ho apprezzato che l’esperienza dell’eruzione si può ripetere tutte le volte che si vuole continuando ad aggiungere bicarbonato ed aceto.
    Per costruire altri vulcani è necessario comprare a parte altro gesso.

    Nel complesso gioco straconsigliato!!! 👍🏻
